BUSINESS AVIATION

ExcelAire is a dynamic aviation organization located at Long Island MacArthur Airport. Aircraft Management and Charter department of ExcelAire is a large contributor to the organizations renowned success. Aircraft ownership is remarkably expensive and cost prohibitive endeavor. The aim of an air charter company is to balance the needs of owner with their expectations of charter activity.

There are innumerable management strategies and approaches used at ExcelAire. Clients will always choose offers and suits that best addresses their needs and suit their taste. ExcelAires reputation is that of a higher-priced operator - a negative aspect in air charter competitive market. The study of ExcelAire offers a unique opportunity to have an in-depth analysis of the various air charter options that are available for people that prefer private flying with great comfort and reliability. The current operational ExcelAire strategy also involves the use of additional aircraft, each of which has the capability to accommodate between seven to nine passengers.

Strategic business plans should be aligned on an in-depth understanding of metrics of deadheads and one-way air charter related jet trips. ExcelAire should adopt a hybrid strategy such as that of a niche low-cost air charter leader. Both international travels and the cross country travel businesses posses a lot of business opportunities to the air charter businesses activities being undertaken by ExcelAire and other companies in the industry. Based on the research undertaken, ExcelAire should implement the use of the continuous flight hour operational strategy. Various optimal operational methods of ExcelAire Company do exist. It is vital that like its competitors, ExcelAire should employ the use of one-way routing and floating fleets to offer significantly competitive quotes on similar charter requests.

Owners of the aircrafts need to have an influence on the operations to be undertaken by their hired aircrafts due to the need for empty legs. Most customers greatly prefer the use of a one-way routing because of the flexibility and reliability associated to this mode of operation. Implementation of one-way routing and a floating fleet significantly improve consumer demand due to the related flexibility, efficiency, and cost effectiveness. Consumers are never simply interested with having one-way routing services and a floating fleet from an air charter but rather are more interested with other related benefits they are likely to accrue from hiring an aircraft from an air charter company. ExcelAire does not operate at rates that are below the charter pricing index thus making it to be one of the most costly air charter companies in the world.

ExcelAire Company
ExcelAire is a dynamic aviation organization located at Long Island MacArthur Airport (ISP). The organization provides and focuses on several aviation services across various functions such as aviation maintenance, aircraft sales, and Fixed Based Operators (FBO) services. Of particular importance is the Aircraft Management and Charter department which is a large contributor to the organizations renowned success. Demand for air charter services has grown exponentially over the years and so have ExcelAires fleet and charter department. However, from this success and growth arises the duality of the charter industry. ExcelAires success creates vulnerability, which is a strong dependence on prevailing economic conditions. To understand the threat imposed on ExcelAires success as an aircraft management and charter organization, one must first understand the nature of the charter industry. Aircraft ownership is remarkably expensive and cost prohibitive endeavor. This aspect of aircraft business has been demonstrated below (ExcelAire Website 2010). A large investment is required in the pursuit of aircraft ownership. As such, a business jet represents a fixed-cost for the owner. Whether the aircraft is flying or not, it cost money to the owner in a number of ways and from this principle, the basic framework of charter arises.

The charter concept is a simple one offset the cost of aircraft ownership by utilizing the aircraft for revenue producing missions. When an aircraft would otherwise sit idle on a tarmac, it is instead normally transporting passengers or cargo at someone elses expense. This is the purpose of an aircraft management company to balance the needs of owner with their expectations of charter activity. It is important to understand that an aircraft management company such as ExcelAire does not own any of the aircraft within its fleet they are simply managing and operating someone elses, who can afford to purchase and own a business jet, highly valuable resource. Like any other industry, there are innumerable management strategies and approaches used at ExcelAire.

Because of the various approaches, each organization offers specific advantages by way of pricing, routing, and fleet mix among others. Brokers, individuals who link prospective charter customers with air charter operators, seek out these advantages and employ them to provide their client with high profile and costly clientele in the best possible. The wide-range of client preference can make best offer mean anything from most attractive or suitable aircraft to best pricing or company operating history. It is evident that clients will always choose offers and suits that best addresses their needs and suit their taste. Nudelman and Don (2009, pp. 311-403) argues that in most instances, brokers will primarily focus on one thing pricing. After the economic downturn of 2009, brokers have continued to be faced with appeasing frugal clients who must now justify their use of private aviation instead of commercial aviation. In an industry of wealth and luxury, now more than ever before, pricing is at the center of focus. Competition that is based on price could be unhealthy if not checked by the relevant authorities.

Compared to similar aircraft operators, though it has an efficient operational strategy, it is evident that ExcelAires reputation is that of a higher-priced operator. ExcelAires fleet is primarily comprised of heavy aircraft, large capacity luxury aircraft designed to travel moderate to large distances. Being based out of Islip, New York, any charter operation requires that the aircraft depart from and return to the home base in Islip at the charter clients expense. Meanwhile, various neighboring operators are employing one-way pricing, where the clients simply pay to move the aircraft from one point to another or the advantages of a floating fleet dispersed across the nation. Already considered an expensive operator, ExcelAire is seriously disadvantaged in comparison to its operators.

Why Charter Business
Charter business presents a very unique platform for the researcher to get a unique picture of the aviation and the air chartering industries. The unique business opportunities presented by the charter business comes with unique challenges, which if not addressed could result into unbearable looses being suffered. Growth factors such as internet communication, the effect of uniting the aviation industry, the use of very light and more flexible jets, the ever growing dissatisfaction in the airline industry, and the growing popularity of the charter business presents unique research opportunities that if well analyzed could help poorly performing charter companies to better their performance standards. The study of the ExcelAire also offers a unique opportunity to have an in-depth analysis of the various air charter options that are available for people that prefer private flying with great comfort and reliability.

The options such as the use of the on-demand charter, having jet membership in a company, and the use of shared ride through the private jet service would also be discussed through the analysis and study of the charter business (ExcelAire Website 2010). There are a number of loopholes in the charter business and this discussion would therefore offer the rare opportunity to address the loopholes and ensure that possible recommendations are made. The charter industry has continued to foresee new developments in technology such as engine design, airframe methods of manufacturing, and the use of better computer aided design and the continued increase of the ATC upgrade (Nudelman and Don 2009, pp. 351-401).
Why the Choice of ExcelAire
   
The uniqueness in the operational and business strategy of ExcelAire makes it to be an interesting company to base the research on. The company faces challenges that arise from the competition being witnessed in the industry. It is evident that competition that is strictly based on pricing could have very adverse effects on a companys performance. However, the focus on ExcelAire aims to identify other vital competitive edges which an air charter business or any other company could focus on in order to ensure that the current customers are retained and if possible ensure that the customer base is constantly increased. Loopholes that exist in the operation of ExcelAire would be focused on in order to address the various ways through which the air charter business challenges could best be addressed without necessarily resorting to the use of price reduction strategies.

Research Problem
RP1 ExcelAires current strategy does not use the hybrid operational strategy that is meant to give it a market niche as a low cost air charter.
      
There are a number of strategies that can be utilized to ensure the success of an airline charter company. An in-depth planning and organizational procedure meant to ensure that resources are adequately utilized and the human resource fully employed towards ensuring that success of the airline charter business is vital. Based on the analysis done by Cecile and Rossouw (2009) on the aspects of air charter management, strategic management, which is the planning, used to help an organization determine its mission and general direction or strategic intent is very fundamental for the operations of a charter airline. Strategy defines the issues and values that are both relevant and important to an organization and provides the basis for managerial decisions. In essence, Flouris and Oswald (2006) maintain that strategy provides the structural framework from which an organization is established and the business angle that would be used to ensure that the organization gains a strong competitive advantage over its competitors. Without it, an organization simply exists without a clearly defined vision, mission, and the goals that need to be achieved.
   
Lichtman (1972) believes that good strategies for an organization do not necessarily imply that success would be achieved. To the contrary, proper planning and implementation mechanisms need to be put into place in order to ensure that the laid down operational strategies are implemented to the latter and success achieved. Indeed, strategy may be considered as vital as the financial capital from which the organization operates. While finances surely bestow a relative competitive advantage, in the absence of strategy, they are simply a tool without a map. Organizations without strategies often follow a path of mediocrity, reacting to external forces rather than dominating the market by way of a competitive strategy (Flouris and Oswald 2006 Charter Industry Downturn 2010). As opposed to mediocre organizations that lack strategy, organizations with well defined competitive strategies have opted to differentiate themselves from the competition through a specific focus or activity. Quite simply, a competitive strategy enables an organization to be different and stand out from its neighboring companies only if its implementation is undertaken.
Hypothesis
The literature will show that ExcelAire should adopt a hybrid strategy such as that of a niche low-cost air charter leader.

ExcelAires Vision and Mission Statements and the Business
The essence of an organizations strategy is captured in its values, vision and mission each accounting for a unique portion of the overall strategy. Values describe how an organization should treat its employees, shareholders and customers. Vision quite simply describes where an organization is headed (Flouris and Oswald 2006). ExcelAire aims to ensure that it provides to the company air fleets that are of larger capacity, very heavy and which can accommodate larger numbers of people, very luxurious, and designed which are designed to constantly travel for both moderate and larger distances with ease. The company aim to ensure that it is ever ready to offer its air services whenever the customers are ready. Through the use of its expert team members that include pilots, flight attendants, dispatchers, and the maintenance crew among others, the companys vision is to ensure that it establishes the largest heavy fleet of jets and to ensure that high levels of flexibility in the airline that would lead to the constant aircraft availability based on the clients needs is enhanced. ExcelAire also aims to ensure that it indeed become a renown dynamic aviation firm all over the world with the major company services being restricted to aircraft management, aircraft, and jet and helicopter charters (Lichtman 1972). ExcelAires core value is to ensure that it offers high quality chartered plans when and where the customers want to. Furthermore, ExcelAire target to ensure that it works towards ensuring that flexibility and convenience of the customer is fully enhanced.

The Current Strategy Used by ExcelAire  
According to Flouris and Oswald (2006), differentiation is a business strategy in which an organization provides a product or service that is unique in the industry thus offering a competitive advantage to the business organization within the competition. This uniqueness enhances a customers perceived value of the product or service and as such, customers are inclined to pay more for it. As witnessed in ExcelAires motto, the organization employs the heavy jet as its prime differentiator. Landau and Nathan (1985) states that indeed, ExcelAire purports itself to have one of the largest heavy-jet fleets in the northeast. ExcelAire boasts thirteen heavy jets and helicopters as part of its fleet and each can accommodate fleet at least twelve passengers at an instance (ExcelAire 2010). The current operational ExcelAire strategy also involves the use of additional aircraft, each of which has the capability to accommodate between seven to nine passengers. The purpose of hiring and ownership of the aircraft that accommodates between seven to nine passengers is to enable the air charter company to be able to attract clients that wants greater levels of flexibility and whose budget and needs may now allow them to hire bigger aircrafts and helicopters (Golob, et al 1981, pp. 213-375). Four additional aircraft, each being capable of accommodating between seven to nine passengers, complete ExcelAires fleet. This indicates a reliance on the large cabin aircraft as a primary means of fulfilling charter demand.

Literature Review
Technological advancement has been known to have a very great influence on the business strategies implemented by air charter companies. Certain unique business strategies that closely relate to technological advancement have constantly been used in ensuring that customers get satisfied and that high flexibility levels in the air charter business operations of a company are enhanced (USSKY Link 2008). For instance, other than offer minimal information that relates to the company operations and business activities that relate the air charter business, the International Air Charter Company provides very adequate information on its website thus ensuring the company clients to better understand its strategies and access more of its services through the company website. The International AirCharter Company distinguishes itself as a leading company that offer both small and larger sized luxury private jest that are highly desired by most executive travelers. To make the services more appealing to clients, the company reinforces the fact that clients do not need their own aircraft, flight department, payment of membership fee, monthly management fee, or acquisition costs in order to use the company private jets ( HYPERLINK httpwww.aircharternet.comair-charterair_charter.htm AirCharter 2009). Low pricing is also a key competitive strategy being employed by the International AirCharter Company.
   
According to the business jet traveler website, the issue of charter pricing is indeed not a simple business affair. Though assumed to be a direct forward process, the pricing of charter air services should be done based on an a detailed study of the business market and the environment within which the business organization operates in. the monetary unit for charter pricing is a very vital factor which can never be ignored when determining the pricing of the air charter services. The weather, the terrain of the physical environment, and the actual distance to be covered in traveling determine the cost that an air charter should impose of its jets and helicopters. Most air charter businesses have different prices based on whether the trip is a return trip or an outbound leg. The arrival of the turbojets introduced the use of hourly rate in determining the costs to be pegged in a hired plane (Charter Pricing and the Downturn. 2010 Doganis 1998, pp. 51-210). Though vital and very flexible, the hourly pricing strategy has a number of shortcomings that always need to be addressed before being implemented by a charter company.

On the other hand, some business models consider the use of the return leg costing strategy as an inappropriate mechanism in the air charter industry. IT has simplified the tracking of empty legs thus increasing efficiency and effectiveness in most air charter companies. In some instances, air charter companies such as Sentient Jet and CharterX employ the use of card information technology program in tracking the unused legs of a charter fleet (Avinode Website 2010). It is clear that air charter companies strategies employed in their operations should not greatly rely on the favorable dead heads that involve the use of a one-way-route- to determine the pricing and business planning strategies. Strategic business plans should be aligned on an in-depth understanding of metrics of deadheads and one-way air charter related jet trips (The Dead Head pricing 2010. The employed business strategies in most air charter companies lay emphasis on efficiency, accessibility, flexibility, and effectiveness in getting assurance of the flights availability. Aircraft owners ought not to expect the charter to offset all their expenses rather than to always rely on flexibility to achieve flight availability. As it is indicated by Leeds Michael of the FlightStar Company, availability of the aircraft to the customers is crucial of the charter owner wants to maximize revenues.

Research Method
    Non experimental data collection method was used in collecting the data that was employed in the discussion and subsequent analysis in this chapter. Literature review process was conducted and used in ensuring that relevant information that relates to the air charter industry is reviewed and compared to ExcelAires air charter information available in published journals, books written, company website, and its annual reports. Through the study of information available on the ExcelAire website and other related online and published journals, the strategic approach of ExcelAire and that of its competitors in the aviation charter market was analyzed and adequately discussed before the findings could be arrived at.

Findings
ExcelAire should adopt a hybrid strategy such as that of a niche low-cost air charter leader. This argument is based on the following discussed literature. The research undertaken has revealed that there is a dire need for the fleet review of the ExcelAire to be undertaken with the aim of ensuring that the cost of its services and the costing methods used to determine the cost of the company charter services are reviewed and the necessary alterations made to the current strategy being used. The research has indeed, revealed that ExcelAire is a dynamic business organization though with a number of challenges and inadequacies that hinder the companys top managements efforts to make it have a competitive advantage in the market in which it operates (G and L 2006). It is evident that competitive advantages in the air charter business mainly relates to the level of flexibility, affordability, airplane availability, and the extent of cost effectiveness of hiring and operating the airplanes.

Both international travels and the cross country travel businesses posses a lot of business opportunities to the air charter businesses activities being undertaken by ExcelAire and other companies in the industry. The need for the company to adopt a hybrid operational strategy is also based on the threats it faces in the current market. Currently, the company has faces the challenge of operating in an ever shrinking business company budget in comparison to the ever increasing demand of more flexible air charter offers from customers (Don 1997, pp. 12-27). Telecommunications also continue to pose great challenges in the aviation industry due to the high telecommunications costs being incurred in an attempt conduct business activities.

Conclusion and Recommendations
Based on the companys strategy being used, the future of the company adopting a hybrid strategy would imply that it benefit from its well organized operational structures and the advantages associated with the ownership of large and medium size airplanes. The implementation should be undertaken through the utilization of its fleets and ensuring that it becomes a low cost heavy operator. The implementation of the findings should be done by using the fleet operations already in place and integrating discounting practices in its cost determination strategies. The company should also maintain current pricing so as not to entirely discourage short-hop flights and to discount bulky offers. ExcelAire should therefore implement the use of the continuous flight hour operational strategy.


RP2 What are the optimal operational methods of ExcelAire
Understanding the manner in which ExcelAire conducts its air charter business activities provides a very good background for understanding the various challenges or competitive advantages, which the company may be having. When the operational method being employed by the company is a one-way routing or not greatly influence the cost of the air charter company thus making it either more competitive or weakening its strategic position within its competition.

Literature Review   
ExcelAires primary competitors employ the use of one-way routing and floating fleets to offer significantly competitive quotes on similar charter requests. By not implementing these strategies, ExcelAire may be losing business and otherwise loyal clientele to cheaper operators. Air charter operations are normally determined by the levels of competition in the market and the needs of the clients within a given business environment. One way aircraft operations and the use of dead ends in the charter industry, according to Stevenson (2008), are not common phenomenon and only happen due to the very substantial reasons that are normally determined by the air charter company. Owners of the aircrafts may also have an influence on the operations to be undertaken by their hired aircrafts. Operations such as in-flight-services, business development operations, and customer service need adequate streamlined operations meant to ensure that the needs of both the clients and the shareholders are kept into consideration.
   
Empty legs in the air charter industry are normally created whenever there is need for the aircraft to move from one location to another for diverse reasons. The reasons for this include moving from one location to another to pick its owner, returning to the station of the air charter company after undergoing a charter servicing, or when returning back home ones it has dropped off a charter passenger. The existence of an empty leg, though not a mandatory consequence, could results in a decrease in pricing from one point to another. According to the information found on the Altitude-Aviation (2010), empty legs point-to-point pricing operational mechanism normally offer very good prices for the private jet charters that are offered by the air charter companies.
   
Air charter multi-leg operations normally target to fulfill the existing demand that exist in an air charter market. On the other hand, ExcelAire charter operates in various parts of the world based on the needs of the clients who hire the aircrafts though it does not offer one-way routing services in its operations. According to the argument of the NewFlight Charters who mainly focuses on one-way routing of their charter services, most customers greatly prefer the use of a one-way routing due to the flexibility and reliability associated to this mode of operation (NewFlight Company Charters 2010). The existence of the deadhead aircraft operations is highly discouraged due to its lack of profitability as the aircrafts fly when empty hence no income is generated by the air charter company that hire out the planes (Stevenson 2008). This is a contrast to the one ways operations in which little operational costs are incurred due to the low operational costs since the aircrafts do not necessarily need to return to their initial base.

To the customers, one-ways operations are preferred since no daily minimum charges are applied. The core identifier of a one way charter is the departing and the arrival points that mark the end or the beginning of the aircraft journey. One way charters such as those operated by V1 Private Jets, CharterX, Avinode, among other related charter companies are normally non-cancellable due to the great price advantage attached to them and their common urgency to arrive at a given destination within a predetermined period of time. In most operations of the air charter industry, one-way charters are normally booked way in advance thus ensuring limiting the level of flexibility meant to be enjoyed by customers (Altitude-Aviation 2010). In the application by an air charter to undertake the chartering business, one of the key requirements that need to be provided by the applying company is a general description that elaborates on the operations of the company for which the authority being sort for. Though the above discussed methods is in one way or another optimal in the nature of an air charter company, Golob, Beckman, and Zahavi (1981, pp. 213-375) insist that an in-depth understanding and analysis of the environment in which the company operates in is very fundamental.

Rizzy Wayne, the president of the AirRoyal, argues that due to the prevailing downturn in the world economy, executives and corporations have strived to eliminate pricey jet related card memberships and fractional share jet programs due to the evidence of their costly operational expense. Air brokers find clients and then work towards influencing the clients in the best way possible through which to choose their air charter alternatives. The operations of an air charter business ought to be guided by high level standards and business ethics. Air charter operators should always adhere to the strict administration rules of the federal aviation. Whether or not brokers are used, high level transparency in the business operations should always be enhanced. Segmentation of aircraft availability is normally done based on the aircrafts number of seats, the validity period, and the book-class. In the operation, Kossowski (2003, pp. 7-14) elaborates on the fact that routing in the air charter industry is normally considered based on the departure and arrival of the aircrafts chartered at their airports and the return time or the period of arrival at the destination for the one-way flights. Poorly performing air charter companies have the operations mainly laying great emphasis on none one-way routing that does not involve floating of fleets thus denying customers the desired flexibility and cost effective operational advantages desired to have a competitive advantage in the market.

Operations of the air charter companies have mainly been aligned on the needs of the people rather than the laid down standards that guide in the operations of the companies. American Air Charter operations, for instance, have greatly been built on the basis of serving people that have to be in specific destinations in a fast, comfortable, and safe way without necessarily paying attention to the cost of the charter flights being offered (American Air Charter 2010). High level of dynamisms and flexibility is a priority to the services offered by V1 Private Jets Air Charter Company which offers large jets, super midsize jets, medium jets, light jets, and the turbo prop jets to its customers with great emphasis being paid to the customers safety. Technology is a key factor in determining the level the efficiency and effectiveness of services offered to the high profile and luxury minded clientele served by the air charter business operators. With flight operations such as Boeing 767-300 and Boeing 757-300 fleets, charter destinations for ExcelAire tends to ensure that it ventures into operations that would provide a faster return on investment to the company without necessarily paying attention to the customer needs and industry challenges in enhancing efficiency and effectiveness in the air charter business operations (G and L 2006).

Research Method
In arriving at the above data, non experimental data collection was used through the use of literature reviews and the study of existing surveys that relate to the research topic of air charter operations. In-depth analysis of the information collected was done in order to ensure that proper understanding of the air charter operations is done before any appropriate recommendations are made relative to ExcelAire. Based on the research problem and the directional hypothesis stated. Air charter company websites, published and non published journals on the websites with literature that pertains to the air charter operations was study in order to establish the various operational methods currently being used by most air charter companies in order to realize high profit margins based on their investments made. The literature review process had the major focus being put on establishing what the major optimal operational methods for the charter companies are, the methods of operations being employed, and the strategic operational decisions being arrived at in order to ensure that the companies adequately meet the standards and operational targets that had been set.
   
Additionally, the research method employed involved the secondary sources of data being analyzed in order to adequately understand the value and advantages related to the one-way routing and floating fleet operations. Secondary sources of data such as online journals, published books that relates to air charter operations, the aviation industry, written magazines, thesis already done by students in the aviation industry, and other sources of secondary data were reviewed with the aim of ensuring that a lot of data that related to the air charter industry was collected. Furthermore, diverse optimal operational methods of ExcelAire were also studied.
Research Findings
The literature has shown that implementation of one-way routing and a floating fleet will significantly improve consumer demand.

Literature That Supports the Hypothesis
The research conducted had a number of revelations that relate to the ExcelAire operations and other air charter companies operations. Efficiency and cost effectiveness in the operations of an air charter highly depends on the level of strategic organization and operations laid down by an air charter. The fact that V1 Private Jets Air Charter Company offers large jets, super midsize jets, medium jets, light jets, and the turbo prop jets to its customers with great emphasis being paid to the customers safety and that such operations has continued to make it be an outstanding air charter company is a clear revelation of the fact that implementation of one-way routing and a float fleet would greatly improve the standards of operations and hence boost the companys rate of return on investment (Private Aircraft and Aviation Charter 2009). To the customers, V1 Private Jets Air Charter Company clearly reveals that most customers prefer the use of one-way routing operational mechanisms that would in return result into higher customer base to the air charter company. Based on the literature collected and analyzed from the International AirCharter Company, it is evident that it distinguishes itself as a leading company that offers both small and larger sized luxury private jet that is highly desired by most executive travelers. To make the services more appealing to clients, AirCharter reinforces the fact that clients do not need their own aircraft, flight department, payment of membership fee, monthly management fee, or acquisition costs in order to use the company private jets. Fleets are thus scheduled based on the customers demand and no clients that hire the aircrafts are forced to pay or literally use the hired planes for a two way journey. The fact that most executive customers of the air charter companys prefer greater efficiency and cost effectiveness rather than merely being offered cheap offers with numerous unbearable fleet conditions that otherwise restrict their traveling freedom.

Literature That Is Neutral
Dedication to private charters by an air charter company is vital step in enhancing efficiency and effectiveness though it does not have a direct impact on the levels of consumer demand. Consumer needs mainly revolve around ensuring that their own self interests of having comfort and timely arrivals at their desired destinations is achieved by the air charter company that rent to them the private jets (Stevenson 2008). CharterX Corporation reveals the fact that the utilization in the information systems such as the ShedAero system neither improves nor hinders the operations of a company regardless of whether or not a one-way routing and a floating fleet is implemented (Avinode 2010).

Literature That Rejects the Hypothesis
According to the conducted study through the review of the literature, the fact that implementation of one-way routing and a floating fleet significantly improve consumer demand does not stand as the ultimate solution to the operational problems in the air charter industry and ExcelAire in particular. There are a number of factors which greatly contribute to the decrease or increase of the consumer demand of the services rendered by an air charter company. The literature has revealed that consumers are never simply interested with having one-way routing services and a floating fleet from an air charter but rather are more interested with other related benefits they are likely to accrue from hiring a jet or a helicopter. Rather than simply offering the customers one-way routing options, the company needs to also concentrate on other aspects of consumer satisfaction. One way pricing only offers an air charter companies the highly desired competitive advantage against its competitor even though it necessarily does not transform to consumer demand improvement. Rather than allocate a lot of efforts and resources to offer a one-way routing services, investments could be made by the company in technology and the telecommunications company departments to ensure that adequate communication infrastructure regulate the pricing being offered for the two-way routing aircraft hiring services being offered (Dellinger 2005 The Dead Head pricing. (2010). Based on the reviewed literature, it is evident that implementation of one-way routing and a floating fleet will do not necessarily improve the level of consumer demand to a companys air charter services.

Recommendations
Based on the in-depth analysis of the study conducted, ExcelAire need to adopt a number of changes or basic alterations to its current operation strategies in order to ensure that it gains a strong competitive advantage in the market within which it operates. For a start, the company ought to begin introducing one-way routing services in its current operations that would mainly involve eliminating the two-way routing services that indeed, have proved not to be very appealing to most customers. The introduction of the one-way routing and a floating fleet air charter services should be conducted in a procedural manner while at the same time maintaining the current two-way routing and the current pricing standards in order not to discourage the existing short hop flights that are the company is widely renowned for. The new operational strategies to be introduced should then slowly involve discounting of customers that request for bulk air charter services and whose flights also involve continuous flight hours by the hired aircrafts. Through the introduction of more dynamic and collaborative operation mechanism, it is evident that floating fleet will significantly improve consumer demand (Stevenson 2008). There is need for the implementation of a standard cancellation policy which should be communicated to the company clients in time to avoid customer disappointment that could in return result into a sudden decrease in the customer base. Additionally, good pricing mechanisms should be integrated into the operations of the ExcelAire operations with the aim of ensuring that the company capitalized on both one-way routing operations and higher levels of efficiency and effectiveness in its business air charter services.

Research Problem
RP3 ExcelAire does not operate at rates that are below the charter pricing index thus making it to be one of the most costly air charter companies in the world.
Economic analysis of air charter business and the specific information that relates to the research topic is fundamental as it offers a strong background on which to predict the profitability of the air charter company and the diverse factors that may in a number of ways affect the operation of an air chartering company such as ExcelAire. Through the analysis of the research problem, the benefits of an air chartering company operating within an agreeable charter pricing index are emphasized. This is of great importance as in establishes an in-depth understanding of the diverse issues that relate to economic analysis and the extent to which adherence to the laid down economic operational standards and pricing indices could influence the success of failure of an air chartering company (The Dead Head Pricing 2010).

Literature Review
The Avinode charter pricing index examines charter pricing on a specific aircraft across several operators. The Avinode charter pricing index is used for conducting comparison points of the venders in the air chartering industry and other related fields. This index is used as a comparison point for vendors. There is a concern that certain operators, in desperate attempts to lure clientele, will operate at rates lower than the charter pricing index indicates, further suppressing the index (Avinode Website 2010). Other than being an unethical business practice, desperate efforts made by any business form in luring customers through lowering the prices of the goods and services offered normally depict the company in questions either as a loss making organization that is in desperate need to revamp its operations or a company that has an unfair competitive advantage against its competitors within the competition (Goodwin 1981, pp. 61-108). Drastic price reductions normally affect an air charter operators profitability since they must strive to remain within a relevant margin of the index. ExcelAire is considered one of the most expensive operators, perhaps further hampering its relevance as an advantageous operator for brokers to work with (Kingsbury 2007). Though not directly affected by the air charter business, IATA and its related aviation related operations plays a pivotal role in enhancing efficiency and effectiveness in the air charter industry. Every year, US 3.6 billion are contributed to the global economic by the air charter industry together with other aviation businesses (Altitude-Aviation 2010).
   
Increased levels of fuel consumption by aircrafts increase the cost of operation and hence the services rendered by the air charter companies become even more costly. Modern aircrafts such as A380 and B777 allow for gains to be made in the long haul market. Investment into much faster jet engines by the air charter operators leads to a more generalized cost of hiring and operating a plane decreasing and hence making the demand of customers for the air charter services to increase. However, the economic value of an air charter company also revolves around its level of fuel consumption. The hire the level of fuel consumption the more costly will the cost of hiring an aircraft in an air charter company. Information systems and software applications that help enhancing accurate online pricing of the aircrafts do exist. Real time costing and determination of the cost of aircraft hiring is a vital tool for enhancing customer confidentially and trust which are also strengthened through provision of accurate trip pricing that is evidently provided by intelligent Avinode.

Very light jets, also simply referred to as VLJ, are more economical to maintain and are normally perceived to be much cheaper and faster jets that enable point-to-point private charter business. In most instances, introduction of new and smaller aircrafts to a charter company does not necessarily guarantee better returns on investment. VLJ, an aircraft manufacturing company, normally insist on the fact the need to create smaller, much faster, cost effective, and reliable aircrafts that would facilitate the point to point movement by the private charter jets thus creating a new better industry. Williams emphasize that development and invention of new aircrafts has the effect of lowing the existing barriers to the actual ownership that would in the end enable the very rich persons to acquire personal aircrafts (2001, pp. 271-276). This will however not result into the wider adoption of the common commercial applications. Consumers of air charter business conducts comparison of at least two alternatives based on the prices being offered before settling on a specific charter services.

According to the Transportation Systems Analysis Model (TSAM 2000), both business and non business trips charters attracts different rates though the rates are within a standardized value based on the charter pricing index. An air charter always ought to carry out a revenue forecast before deciding on the charter costs to be used. Other than the need for exclusive chartering services, flexible, convenient, and comfortable services, wide ranges of air charter process varied from one charter product to another which includes exclusive charter, exclusive travel, business jet, and the private jet charters. According to the AirCharter Company, the hourly rate ranges from  2,000 to  13,000 hourly rate (AirCharter 2009). These prices are adequately within the charter pricing index. The prices are also in line with the flight sizes of between 5 to 23 persons per flight based on varied aircraft speeds (USSKY Link 2008). An estimator for the flight charter flights establishes the diverse trends and mechanisms through which prices should be determined with the aim of ensuring that charter operators do not offer extremely high or low charter service prices that would earn the company an unfair competitive advantage or result in making super high profits. This economic trend involves both the freight air and the passenger air charters (ExcelAire Website 2010 Altitude-Aviation 2010).

In ensuring that its charter services are in strict adherence to the charter pricing index, the EA Elite Aviation Company works towards ensuring that it minimizes its operating expenses by implementing cost effective charter operating mechanisms. The company uses fuel programs that involve the use of better negotiated costs structures that mainly have better negotiated structured costs, fixed base domestic operators, and manageable fuel credit cards (EA Elite Aviation 2010 Lee and Mckenzie 2006). Such strategic economic analysis and expense saving mechanisms are vital in enhancing cost effective air charter operations (Accounting management and the goals of chapter 2010). According to the Altitude Aircraft (2010), most aircraft chartering companies in the US operates between 300 and 600 for every flight hour and this does not always include the related chartering expenses. On the other hand, the twin piston chartering aircrafts rates prices ranges from 600 to 1200 for every hour the aircraft is used plus other expenses while the Turboprop chartered aircrafts goes for 130o to 3000 based on the similar above stipulated chartering conditions. Air charter prices in most chartering companies, as is indicated above, greatly depends on the flexibility and reliability that needs to be offered to the consumers rather than the ultimate profits which the company intends to make (USSKY Link 2008 The Dead Head pricing 2010). ExcelAires pricing factors tend to be different as is commonly reflected from the chartering company.

Research Method      
Due to the nature of this research, non experimental data collection strategies were employed with the aim of ensuring that the process of analyzing economic factors that relate to the air charter company and particularly the Excelaire was collected and then discussed in order to arrive at the various conclusions that form the research findings that answers the research problem. Data collection on the economic analysis was conducted through the use of literature reviews and an in-depth study of other secondary sources of data. The analysis of the information collected was done in order to ensure that proper understanding of the air charter economic issues such as price and costing factors are adequately analyzed and fully understood before the determination of whether or not the economic status of the Excelaire pricing strategies fully adhere to the air charter pricing index (The National Pricing Index Archives 1983, pp. 417-999).

Air charter company websites, published and non published journals on the websites with literature that pertains to the air charter economic issues and pricing methodologies and standards adopted were studied in order to establish the various pricing strategies and trends of strategies currently being employed by most air charter companies in order to realize high profit margins based on the various investments made in the air charter companies (Lee and Mckenzie 2006). The literature review process had its major focus being put on establishing whether or not the existing air charter companies adhere to the aviation pricing index and other factors that determine the pricing levels implemented by the companies. Furthermore, secondary sources of data such as online journals, published books that relates to air charter operations, the aviation industry, written magazines, thesis already done by students in the aviation industry, and other sources of secondary data were also reviewed. The secondary sources of data analyzed aimed at establishing the various possible better pricing mechanisms that could be employed by the air chartering companies in order to reliable better profits through ethically correct competitive advantages without any undue influence to the market.

Findings
The literature research has shown that ExcelAire does not operate at rates that are below the charter pricing index thus making it to be one of the most costly air charter companies in the world.

Literature that Supports the Hypothesis   
Excelaire Company does not adhere to the charter pricing index but rather uses its own pricing mechanisms with the aim of ensuring that it maximizes its profits. The research has indeed, revealed that competition is a vital factor that influences consumers purchasing patterns. The literature reviewed reveals that Excelaire has in most occasions hampered the efforts of air charter brokers to sell its services due to its costly pricing within the competition. The company does not adhere to the charter pricing index due to the fact that it mainly targets the expensive corporate customers that mainly concern themselves with conform and convenience rather than the cost of the air charter services offered (Williams 2001, pp. 261-273). Under its building itinerary section that has the one-way, roundtrip, and the multi-leg services being outlined, the cost of the one-way trip, which are also scarce, are highly exaggerated in order to discourage customers from using such charter services. Other company services such as provision of fully equipped maintenance departments, aircraft hangarage and parking, concierge services, rental crew, computer flight and weather related services, wireless internet access services, and the after hour fuel and the emergency services are some of the economic analysis issues Excelaire capitalizes on in justifying its lack of adherence to the charter pricing index (Accounting management and the goals of chapter 2010).

Neutral Literature
According to Lichtman (1972), the charter pricing index is mainly controlled by other environmental business factors such as the jet fuel index of pricing, consumer patterns, and related services offered by a charter company to its clients. The charter pricing index mainly stipulate the preferred market prices of air charter businesses but hardly puts into consideration other environmental factors needed to ensure that economic market of the air charter industry is normalized (Liu,et al 1988).

Literature That Does Not Support the Hypothesis
Other than proclaiming that the Excelaire is ready to offer charter services whenever they need arise to all parts of the world and that it handles corporate road shows, family gateways, ground transportation, gourmet catering, special chartering requests, and concert tours the company hardly communicates its pricing index to the public or through its website (EA Elite Aviation 2010 The National Pricing Index Archives (1983, pp. 532-782). It would be hard to substantiate the claim that Excelaire does not adhere to the charter pricing index with paying adequate attention to its core services and the vision and mission of its existence and its business strategies. In fact, based on the argument of Douglas and Shappell (2003), an air charter always ought to carry out a revenue forecast before deciding on the charter costs to be used.

Recommendations
Other than the need for exclusive chartering services, flexible, convenient, and comfortable services, wide ranges of air charter process varied from one charter product to another, which includes exclusive charter, exclusive travel, business jet, and the private jet charters, should be offered by an air charter company. Based on the above economic analysis, it is evident that various adjustments ought to be undertaken by Excelaire if it has to remain relevant and competitive in the market. To begin with, the company needs to adjust its air chartering prices to ensure that the prices offered adhere to the air charter pricing index (Cecile and Rossouw 2009 Charter Pricing and the Downturn 2010). Secondly, in its implementation of one-way charter services, services that only increases the operating costs and introduce undesired luxury while at the same time increasing the aircraft hiring costs should be eliminated. ExcelAire should conduct a thorough salary and expenditure survey and an analysis of the air charter trends and statistics in order to make guided decisions on the extent to which to adjust its pricing index with the aim of remaining competitive, relevant in the market, and cost effective in its air charter operations.

Pricing   
To better the performance of ExcelAire and enhance its market relevance through strategic corrective measures, there are a number of issues that needs to be addressed. In line with the conducted in-depth analysis of the business aviation relative to ExcelAire, it is clear that in order for ExcelAire to maintain and keep its operations profitable and viable in todays economy, other than regulating its operations and introduction of unique air charter services, great attention should be accorded to the cost of fuel which has proved to be a continuing concern for many air charter operators. Since the price of oil in the modern shaky economy is likely to continue influencing the pricing indices of air charter services, adequate attention should be accorded to the operations of Excelaire to ensure that only cost effective operations are tolerated and the constant analysis and survey of the air charter market be done in order to review the company pricing index (Douglas and Shappell 2003). Mechanisms to cut on the fixed costs of operating aircrafts and the overall process of hiring them should be re-analyzed with the aim of ensuring that streamlined mechanisms are employed to fully minimize on the fixed costs. These mechanisms include Excelaire renting out unused aircrafts and where possible venturing into the aviation industry that would ensure that other services such as parcel transportation is done. Discounting of customers that request bulky air charter services and whose flights also involve continuous flight hours by the hired aircrafts should frequently be done. Such strategies would greatly reduce the burden that results from the fixed costs air charter operations.

Cost, Comfort, and Flexibility   
Douglas and Shappell (2003) believe that it is always vital that the needs and concerns of air charter customers be given higher priority in planning for the company operations. It is important that Excelaire ensure that the ever increasing needs of customers to travel at will and with great comfort and flexibility be delivered to them. However, to achieve this, Excelaire should employ the use of small flights that would in return ensure that the charter company attracts more clients based on the improved levels of flexibility and alertness and sensitivity to the consumer needs. Additionally, Excelaire need to pay great emphasis on the quality of services, flexibility of their operations, and offer greater attention to the needs of the customers through more personalized services. This would involve sticking to the operational standards while ensuring that there are provisions to address possible unique customer needs that may arise from time to time. This also revolves around the fact that, as a strategic mechanism, Excelaire should use a one way pricing strategy in an attempt to enhance greater levels of flexibility and hence make ExcelAire to become more flexible. One-way routing and a floating fleet air charter services should fully be introduced in Excelaire operations though in a procedural manner in order for it to maintain the current two-way routing and pricing standards and hence avoid discouraging and disorienting the existing short hop aircraft customers. Public relations strategies should be undertaken to eliminate the common perception that ExcelAire is a very costly air charter company.

Information Technology and Global Alliances
It is evident from the research undertaken through the review of literature and surveys on the business operations of ExcelAire that the company has integrated information communication technologies in its air charter services. However, the company should invest more resources in more intelligent technologies and information systems that would strengthen its bond with customers and enhance high level transparency and openness. This is crucial since it is only after a company wins the customer loyalty that it can gain a greater competitive advantage within the competition through other competition operations and strategic mechanisms implemented. To ensure that it better its global presence, ExcelAire need to establish more global alliances in order for it to find exploit new markets. It should therefore be able all learn and improve the load factor, efficiency in scheduling efficiency, and reduce their air chartering costs and maintenance costs. To attract more clients, the company ought to enter in alliances and partnerships with corporate organizations and other air charter companies in order to gain a global view and increase its rate of return on investments made.
In trying to review the existing literature, this dissertation will adopt the four-pillar approach as outlined by Osterwalder, et al (2005) in their nine business model building blocks structure (p.18). This will be necessary as it will induce a sense of focus and direction to the review and hence limit it to the study topic. In this regard the review will be limited to literature on the products offered by airlines industry how the industry stakeholders go about creating interactive customer interfaces the key strategies employed by the industry players the management of interactions infrastructure, and the core financial management tools employed by the industry players to maximize profits while keeping costs at manageable levels.

The aero-engines industry for instance is a unique industry in that, it entails large sums of capital to manufacture aero-engines, to build aircraft frames, to carter for fuels and labor expenses, as well as taxes paid to domestic and foreign governments for using their airspaces (Almeida, 1997). See appendices for a detailed table The high amount of capital may be prohibitive to industry players particularly during hard economic times. For instance, to fully assemble and equip an aero engine with the necessary parts and components requires more than 35 million while assembling a 7 x7 aircraft frame may costs a whopping 250 million. By fair terms these are relatively high costs which need to be distributed among a number of industry players so as to cushion the eventualities of shocks and risks.

These costs may even be much higher particularly if the aircrafts fail to reach its minimum operation lifecycle due to marketplace as well as natural calamities (Buxton et al 2006). In fact, it is known that aircrafts are prone to all manner of risks that range from human to natural catastrophes. For instance the industry is highly affected by extreme heat, extreme cold, fog, volcanic emissions, and hailstorms among other severe environmental conditions. Moreover, it is true that unlike automobiles, aircrafts undergo rigorous and regular maintenance and inspection. This is necessary as a small hitch on an aircraft can cause immense losses as opposed to the case of automobiles that can be fixed in the middle of a journey in the event of a breakdown (Farr, 2006).

Background of Aviation Industry
Two major events in the aviation industry in the United States have serious repercussions in the aviation businesses. Firstly, Scott et al (2006) and Buxton et al (2006) agree that the airline industry is faced by a barrage of financial and operational challenges. Apparently, the industry faces these challenges at a time it is being weaned from the close support it used to enjoy from the domestic governments. As a matter of fact, the state coffers have over the past been used to cushion the airline industry from marketplace challenges such as financial crunches as well as cut-throat competition. This is a trend that can be attributed to major airlines considered as national flag carriers that have in the past not exposed to the marketplace vulnerabilities. In the US for instance, an estimated 5 billion were distributed to a number of major airlines between 2000 and 2003.  This was mainly done to prevent the airlines from going into bankruptcy as stipulated by the provisions of Chapter 11 of the US Constitution (Scott et al, 2006).

As such, there is no doubt that the state financial and administrative leverage played a huge role in streamlining the airline industry. However, this trend is slowly changing particularly following the realization that the Over-capacity and low yields lead to instability and the effects of any disturbances within the global economy cannot be absorbed through bailouts (Buxton, et al 2006, p.2). Needless to say this is a wakeup call to airlines as well as other major players in the industry to adopt more competitive and cost effective business models as a practical solution to the overreliance of support from the public coffers.

The other major event was the famous September 11terrorist attacks (Thompson, Strickland,  Gamble, 2003 C-644). Because of low airline traffic, airline companies were financially affected so much so that many airline firms went into downsizing, cancelling orders of additional aircrafts, cutting down number of flights, went into borrowing money to cover cash trapped coffers, and as a last resort, filed for bankruptcy. It was a dark period in the history of U.S. aviation which also affected the aviation global business landscape. On top of this, the 2008 global financial crisis caused great financial crisis to the commercial aviation industry, still reeling from the after effects of the terrorist attacks. Such was the scenario in the last decade in this highly technical industry (Thompson et al 2003).
    
A combination of these two major events as well as a gamut of other marketplace impediments threatens the smooth operations of the airline industry and in particular the MRO aspect of the industry that apparently is directly responsible for between 10 percent and 15 percent of the overall airline expenditure (Knotts, 1999). Bearing in mind that the aero engines are the aerospace industry drivers that creates revenue for all the stakeholders through the normal engine flight hours (EFHs) and engine flight cycles (EFCs) as well as maintenance and consumables whilst in service there is a great need for aero engines to collaborate with aircraft frame builders, airline operators as well as other ancillary services providers (Buxton, et al 2006, p.4).

These collaborations may take the form of a complete or partial reinvention of their various ways aero engines industry conduct their business activities. Admittedly, the changing business scenario calls for drastic changes in the aero engine business models. No longer competitive by merely just trying to deliver products, conduct repairs, and go into overhaul, the industry has to explore new business approaches if it desires to be globally competitive. The industry has to adopt the changing market place and realities and adopt fast (Steffens  Hollmeier, 2009). This kind of reflection on past business models, to determine which worked well or did not work, or even which should be re-invented or re-engineered must preoccupy aero- engine management nowadays if it desires to exploit market opportunities and take new directions on how to compete in the future.

 In light of the above discussion, new and interesting directions suitable for the industry strategic positioning can be advanced. These are drastic reduction of new engines development and production costs revision of the value- added chain consolidation of the industry and entry into cooperative programs and product differentiation through innovative technologies (Steffens and Hollmeier, 2009). In addition, Steffens and Hollmeier suggest outsourcing MRO and engaging in strategic alliances with other corporate partners in the industry.

Let us take this one by one. In terms of drastic reduction of new engine development and production costs, there is a need to be cost-effective in coming up with new aero engine parts but at the same time not sacrifice quality. Where are the areas where costs can be drastically reduced These can be done in the variable costs as well as in the production costs.

 Regarding product differentiation mentioned by Steffens and Hollmeier (2009) as one of the strategies to be adopted by the industry, this is affirmed by Porter (1985 14) who remarks, A firm seeks to be unique in its industry along some dimensions that are valued by the buyers. For the aero engine industry, this strategy can be translated as offering unique spare parts after-sales support system. Product differentiation can be a way to be ahead of the competition. When aero engine companies think of innovative and unique products, they are in actuality, trying to differentiate from other similar products manufactured by other competitors. On his part, Johansson (2004) acknowledges that it is true that for OEMs within the aerospace industry as well as other industries to wade through the murky global market economy they must embrace specialization. However, for this specialization to bear the fruits of innovation it needs to be collaboratively shared. In this regard aero engines OEMs, their customers as well as other industry players need to pool together their different specialities in what Johansson  terms as open and amorphous networks of peers (p. 257).

On the hand, the revision of the value-added chain pertains to the life cycle of the product as well as whether the company make some changes either through new technology, or by coming up with some modifications in the whole value chain. Another way is to consolidate the industry and for companies to enter into cooperative programs. Industry consolidation and collaboration will demand that the companies within the industry should find ways to work cooperatively and collaboratively with one another. This is easier said than done. Entering into new cooperative projects involving other companies would mean getting into strategic alliances with them over the long term.

Current Trends in the After-Sales Service for Aero Engines
 Innovative Business Models
Mabert, Ashok, and Campbell, (2006) identify a new source of income for the commercial industry that can be a source of competitive advantage. Farris et al (2005) likewise provide the aftermarket support practices and directions as well as the greater opportunities for supply chain management. Mabert et al (2006) pointed out that it is in aftermarket support that the opportunity to reap profits will emanate, not in the initial sales of spare parts for the aircraft. This is a radical way of thinking of how to compete. To think that they are an after support company, rather than just a company that delivers spare parts. Precisely, collaborative services between aero engines OEM, aircraft frame builders and airline operators should not only involve the conventional settlement of customer claims and warranty fulfillment, rather it should be holistic. It should encompass regular maintenance and overhaul services, procurement and timely delivery of spare parts, as well as other contract-long customer engagements. Such holistic after sales services are beneficial to both the end product companies as well as the OEMs. For instance, General Motors Corporation recently registered a huge profit from its 9 billion worthy of after sale services when compared to what it got with its 150 billion sales from its wide range of automobiles (Viardot, 2010). Ideally, technology and capital intensive companies have over the years managed to withstand market shocks by staging interactive and contract-long after services sales.

The underlying idea behind success from after sales services is that companies are able to supply their products and make conscious efforts to put in place strong preventive and supportive measures for such products (Bundschuh  Dezyane, 2003). This helps to increase the value of the products sold while also creating strong customer relations for future business. As Viardot (2010) argues it is very easy for firms to find market for its products in segments that it already has strong relations as predicting market needs is easier than it is in new market segments. A case in mind is that of Toshiba where in 2002 the first month sales from warranty fulfillments went up by a margin of 37 percent, with overall sales averaging at 4 percent. The company had embarked on an aggressive drive to initiate an electronic based after sale services for its laptops. The drive entailed prompts to new users requesting them to create a profile that Toshiba used to make critical decision on the effectiveness of a range of warranties it offered (Viardot, 2010).

After-sales service activities in the consumer goods industry depict an orientation to improve company image, customer satisfaction and retention (Saccani et al 2006). This is highly important, indeed, and I agree with the authors in pointing out that the focus of companies offering after-sales service tasks should be to enhance the companys credibility and good image as well as make the customers happy and retain them through customer repeat purchases or their availing of the services. Besides, the after-sales service when done in excellent manner and of high quality would attract new clients. There are only a few big players in the global aviation industry and getting them to avail of the after-sales support service would redound to higher company earnings.

In support of this postulation, a study carried out by AMR Research, Inc. concluded that companies that practice after sales services are bound to realize up to an average of 24 percent in revenues and about 45 percent in profits. Rolls-Royce for instance registered a relatively higher profit margin (55 percent) in 2004 courtesy to its concerted efforts in practicing after sales services. Similar results were registered by Bombardier, another aero engines company where about 80 percent of present net value was recorded compared to 20 percent of the original investment value. Even so, this trend is not uniform across all aero engines and aircraft frame industries possibly due to the features of the after sale services model adopted. For instance, Airbus recorded a relatively low after sales services present net value of about 30 percent compared to its high values of about 70 percent of its new investment (Viardot, 2010).

Collaborative Business Practices
An intensive review of the literature on covering strategies employed by aero-engine companies reveals that they are now into collaborative business practices. These practices are comprised of strategic alliances, revenue and cost sharing practices, and virtual enterprise collaborations, which are enabled by information and communications technology. Scott et al (2006), supports this postulation when they argue that a combination of technical and financial snags pushes the aero engines OEMs into forming joint ventures. As it is now, the few major aero engines OEMs have formed joint ventures an indicator that indeed it is very difficult to survive as a lone ranger. On the other hand, such joint ventures are a blessing to the engine OEMs who pool their resources together and hence avoid the cut-throat market competition. It is indeed true that joint ventures do reduce the amount of profits realized by the individual aero engines OEMs however, given the inherent risks in the aerospace industry aero engines OEMs forming joint ventures gain a reprieve in the form of risk sharing than otherwise it would have been if they ventured on their own. 

Larson et al (2010) acknowledge the importance of forming business alliances among OEMs. They assert that such alliances helps to influence their customers to make use of shared information, know-how, as well as other critical organizational materials. In their arguments they support the formation of Virtual Enterprises (VEs) which they argue accord OEMs an opportunity to choose which areas of their overall operational activities they should cooperate with their counterparts and which areas they should handle alone. A good example of an OEM in the aerospace industry that embraces this model is Rolls-Royce which pursues outsourcing and sometimes even outshoring about three quarters of its supply chain management while managing the remaining percentage. Specifically, Rolls-Royce ponders various aspects of the overall assembling of engines such as ... the hot end of the engine, the turbines, the compressors and fans and the alloys... and determines how they are made with view of outsourcing those elements that can be produced by others at a cheaper price (Johansson, 2004, p. 459).

Interactive practices speed up development cycle times, minimize and reduce product cycle costs. This is good news for other aero engine companies. They can now hook up with the virtual enterprise collaboration hub through an engineering portal. This is a virtual portal that at any moment can be accessed by strategic partners. This is the kind of collaboration that we are looking for in order to make the aero-engine industry globally competitive. It is good to know that MTU Aero-Engines has pioneered in this worthwhile strategic business alliance. If we look at the aviation industry three decades ago, this was not possible. The presence of the Internet today makes many things possible for the industry which otherwise were virtually impossible in the past.

On his part, Hill (1994, pp. 466-467) points out that strategic alliances for global manufacturers are a way to build trust between firm and suppliers. Trust is built when a firm makes a credible commitment to continue purchasing from a supplier on reasonable terms.  It can be seen that for the aero-engine strategic alliances, there are advantages that can be derived if the companies adopt this strategy. However, there are also their attendant disadvantages. For instance, (Farris et al 2005) remark, strategic alliances involve greater risks, dependency, and rewards than do tactical alliances. Similar sentiments are shared by Buxton et al (2006), when they postulate that an agent-based business model not only reduces unnecessary costs but helps to predict future market trends. However, they are quick to point out that such model needs committed product managers capable of reading through market trends and making sound and timely judgements. In addition they champion for the VIBES (Virtual Interactive Business Simulator) tool that they argue can be successfully intertwined with the agent-based model to come up with new business alliances that can be utilized build future markets. Precisely, they envision a model where the modeller focuses less on event sequences and instead aims to capture the behaviour of each actor in a system as an agent with a degree of autonomy. Combining these three different modelling approaches together enables complex business environments to be modelled.

Scott et al (2006) offers that performance among aero engines OEM increases with MRO services  high fliers in the industry are those that embrace proper MRO policies. In explanation they use a scale that shows peak financial achievements at either end of the curved scale. This can be perceived as a support to two of their three business models of virtual airline and aviation business group they advance in the same work. In this regard it can be deduced airlines practicing traditional business models are at a disadvantage as it becomes very difficult for them to compete at a level ground with their counterparts who have embraced new innovation particularly those that involve the delivery of non-conventional and opportunistic services to industry players.    

Another model of collaborative business practices that I was able to find in the literature (Steffens and Hollmeier, 2009) is that of the European consolidation along the lines of a European System. They call it the European System Coordination and Management Company. In my opinion, such a European management company may be disadvantageous to the United States aviation industry, though. But I believe that it is a good move to take in order to consolidate and ensure that collaboration is effective and well coordinated.

Forecasting and Simulation Models in the Aero Engine Industry
Because of the uncertainty and great risks entailed in the aero engine industry, companies have tried to develop forecasting and simulation models to predict eventualities related to spare parts planning, scheduling, repairs and overhaul. Marbert et al (2006) mentions a forecasting model for spares demand planning using the SAP Advanced Planning Optimizer (APO) software system. Buxton et al (2006) focus on life cycle cost simulation. Stranjak et al (2008) presents the Overhaul Prediction Model and Scheduling Tool for simulation of complex aero engine operation.

On the other hand, the forecasting tool as described by Stranjak when compared with other forecasting models earlier mentioned appears to be powerful in terms of its capabilities to predict whole engine corporate risks, work scheduling, scenario modelling, and conducting what if analysis. These are the kinds of forecasting techniques that management need to enable them to mitigate unforeseen circumstances and events. These are statistical techniques that perform simulation and through this process, are able to predict events.

Another forecasting model is the dynamic modelling technique the  the Global Manufacturing Networks (GMVNs).  GMVNs are virtually volatile organizations that aids in integrating companies so as to enhance the sharing of critical resources.  The advantages of GMVNs are their being highly flexible system with low barriers to entry and exit, geographic flexibility, low costs, rapid technological diffusion, high diversification, and exceptional economies of scale (Monroy  Arto, 2008). Geographical flexibility calls for virtual teams deployed in some key areas in the globe that can respond with ease and speed.
But when we use this network, there are risks involved and we have to be wary of them. These are risk of contract manufacturers developing their own end-products in competition with their customers the risk of technology transfer, and the risk of losing process expertise. (Monroy  Arto, 2008) I think this can happen when they will outsource manufacturing processes more and more to the network and a memory loss might occur. Caution is therefore called for in this instance.

 Driouchi et al (2008) suggests that dynamic risk management policies for designing and appraising flexibility in service planning and provision should be adopted to allow for better decision making in the face of uncertainties. Dynamic forecasting models are indeed just that, management should have to evaluate the most effective prediction model for the company to adopt. This kind of forecasting technique uses non-linear dynamical models to capture fluctuations in demand and scheduling that cannot be captured by linear statistical models. In addition the authors indicate that services and products are merging and manufacturers are seeking to grow and protect their profitability by enhancing the service elements of their customer offerings. They give the example of Rolls-Royce Power by the Hour contract. Instead of selling aero engines to customers, these contracts enable the customers to pay for the engine capability, based on the hours flown, while the manufacturer retains the responsibility for maintaining the engine.

Modern Models of Business among Airlines and Aircraft Framers
Drawing from Doganis (2001) work, Scott et al (2006) advance three major business models adopted by major airlines in the world traditional airline virtual airline, and aviation business group. The traditional airline is a major business model that is being pursued by large airlines such as British Airways, Delta, and Iberia. This business model is more or less atypical to the government controlled airline that enjoys immunity from marketplace shocks. Practically, it entails regular and uninterrupted access to air travel services that involves collaboration between airlines where airlines agrees to run connection legs for other airlines within the same operation alliance. Again, through the alliance the airlines make it possible for their clients to book their travel arrangements through a single point even if the travel arrangements covers a relatively large route which is obviously not served by a single airline.

A good example of traditional airline model is the star alliance where 18 airlines share codes, marking, airside maintenance, and other relatively low costs services. Basically,  This accords the clients to numerous benefits as it reduces the hassles of flight interruptions, long waits for flights connections, costs incurred in car hires, and most importantly it allows for the cross transfer of air travel points that are calculated based on the number of travels using any of the alliance airlines as opposed to a single airline. The large network of routes also eliminates the chances of flight cancellations and also accords the airlines the opportunity to enjoy the economies of scale hence maximization of profits while still offering other ancillary services such as meals and entertainment for their customers at subsidized charges or even free of charge for some special flights.

According to Scott et al (2006), virtual airline model of business entails exceptionally low prices, a feat that is achieved through concerted efforts to cut down operational costs as well as the scrapping of a number of costs such as in-flight meals and entertainment passed on to the customer in traditional business models.

Lowering air travel prices among airlines that practice virtual airline model is also made possible by a relatively high visibility of support service costs where the airline only partakes of doing those activities that are absolutely necessary and which it can do with minimal costs and with great ease while liaising with other stakeholders in the industry such as aero-engine manufacturers, aircraft frame builders, human resource consultancy firms, and others in bid to optimize efficiency while keeping the operation costs at a manageable level. Such close business liaison eliminates the notion of fixed costs as it offers costsprices alternatives for critical services such as repair, maintenance and overhaul of aero engines parts. Some airlines such as the Ryanair of German have already indicated that it will ponder the possibility of offering absolutely free flights as part of its virtual model pursuits. Low air tickets prices compounded with free meals and entertainment goes a long way in building a strong customer confidence and loyalty. Even at the backdrop of economic downturns this business model has attracted significant results among airlines that have been practicing it.
Graf (2005) supports this business model when he holds that airlines that have been practicing this form of business model are cable of realizing profits and hence remaining competitive during economic downturns.

For instance, airlines practicing conventional models of business in the US for instance have registered significant operational problems in adjusting to economic shifts when compared to their counterparts in German such as Ryanair and EasyJet that are better known for their relentless commitment in pursuing the virtual airline model (Scott et al 2006). On the other hand, airlines that opt to drop their traditional business models have got a chance to reap multiple benefits. They have an opportunity to penetrate relatively low-cost market segments hence maximizing their revenue base. Again, by moving their aircrafts, capital, employees, as well as other assets from traditional to virtual model of business, the airlines stand a better chance to forgo huge costs that they may have otherwise incurred. This is due to the inherent success and benefits associated with the virtual airline model (Graf, 2005). As a matter of fact, this evidential success has enticed big airlines in the world such as the KLM as well as Southwest (Scott et al 2006).

Lastly Scott et al (2006) discuss aviation business groups as their third business model practiced by airlines. In this model they argue that when looked from the customer viewpoint, this business model is more or less similar to the traditional model given that they both employ a collective ticketing. This business model however, indulges agents as well as online services to sell and carry out market promotions targeting mostly travellers on business trips. Practically, and in bid to maximize revenue creation this model also involves other services apart from those targeting business travellers. For instance, it also provides connection services to other airlines particularly to destination in the interiors of major business hubs. Riding on the wave of outsourcing g in the airlines industry particularly among airlines practicing the virtual airline model, the aviation business group business model seems to offer sound returns to airlines practicing it. For instance, Lufthansa and Singapore airlines provide a good example of airlines that have cut themselves niches by riding on the wave of outsourcing that has hit the contemporary airline industry. By being a potential outsourcing services provider for other airlines practising the virtual airline model aviation business group model airlines can utilize its staff as a source of revenue generators as well as doing their in-house maintenance.
2.2.5. Recent Aerospace Industry Models

Yusuf, Gunasekaran, and Abthorpe (2004) argue that contemporary market economies have changed over the years. Such changes has occasioned significant change of marketplace operations to an extent that internationalization is inevitable. They argue that initially companies were only concerned with creating quality products and selling them at reasonable prices. However, this is not the case in the contemporary marketplace. Companies must offer more than quality and affordable goods and services. They must ensure that their services are flexible and realistic to market forces such as diminishing sales, increased competition, high costs of production, etc. while still ensuring quality and value for money.
Using the case of Rolls-Royce the authors demonstrates how Enterprise Resource Planning (ERP) can be applied in the aerospace industry with satisfying results.  Rolls-Royce had struggled for a long time with different operations systems without achieving significant results. The company incurred huge costs, despite the products being practically inefficient and incompatible with modern aerospace industry trends. However since it adopted the ERP model, Rolls-Royce handles all its complex operations in more efficient and predictable ways (Yusuf et al, 2004). The gist of the model is that it links together all processes involved in the critical production processes such as finance, human resource, procurement, manufacturing, inventory, supply, etc. this helps to cut down inventory levels, reduces redundancy, as well as inducing efficiency (p. 264).

According to Almeida (1997, the US aero engines industry has lost a significant chunk of its past glamour. It used to occupy the global number one position in the manufacture of original aircraft equipments, however du e to he calls uncertainty (p.2). However, given that two of the global leading aero engines OEMs, Pratt and Whitney General Electric continue to command significant market presence indicates that they have devised ways of mitigating this uncertainty. It is arguable that mitigating such uncertainty demands sound marketing strategies, risk management strategies, and above all organization integration strategies. Such organizational integration which entails close partnership between aero engines OEMs can go a long way in stabilizing prices as there are no threats of some company pricing its goods at lower prices to woe customers. Again, organizational integration allows for joint financing of key production processes and materials making the companies to reduce their overall cost of production considerably.

It should be noted that the demand for aero engines and aero engines parts is not high given the high prohibitive costs involved in its overall assembling, a thing that makes ownership of aircrafts a preserve of the societies most wealthiest. As a matter of fact, aero engines industries serve only four major categories of customers aircraft frame builders, airlines, governments, and armed forces. By fair terms this is relatively a small market. Consequently, aero engines companies that do not engage in organizational integration practices may find themselves playing second fiddle to their rivals. Again, basing on the fact that the aero engines market is highly cyclical (Almeida, 1997, p.4) it can be very difficult for companies to break such existing cycles particularly if it does not offer competitive services. In competitive services aero engines companies can offer high discounts to their customers on condition that they also include binding after services sales contracts.

This arrangement is advised by the unique nature of the aero engines industry where engine manufacturers gain up to three times the value of the engines from the normal sale of spare parts and maintenance services during the lifespan of the aero engines.  As of 1997, Pratt earned from half to two times from the proceeds of the value of engines it sold through after sales services (sale of spare parts and maintenance), GE earned about three quarters of the value of the sold engines, while a PW earnings from spare parts sales amounted to 40 percent of the total earnings before taxation (Almeida, 1997). Similar sentiments are shared by Ward and Graves (2005) though using a different terminology, through-life management (p.4). The through-life management model entails the life-cycle management of products, services and activities required in delivering a fully integrated capability to the customer, while reducing the costs of ownership for the customer (p. 5). The bottom line of this model is that the customers are accorded more value for their money throughout the product life.

The Sikorsky Skycrane

Problem statement   
With many different helicopters being built over the years, constantly at the back of the manufacturers mind has been the question of efficiency and effectiveness. This paper tries to bring out the Sikorsky Skycranes effectiveness by comparing it to other helicopters in terms of performance, design and other aspects.

Motivation
The Sikorsky Skycrane has been widely used in the Military and civilian fields for at least half a century since its first flight in 1962. (Taylor, 1976)  This is makes us ask the question why and this research paper holds the answers.
Approach
The research looks at prototype construction and analysis of field data for the Sikorsky Skycrane. Included are both product specifications and actual production data of the helicopter since construction of its first prototype.

Results
The research proves that the Sikorsky Skycrane is economically efficient and reliable as compared to most other helicopters. This is attributed to the helicopters flexibility and a wide field of usage with the least additional modifications.
 
Usage of the Sikorsky Skycrane is definitely bound to increase. Current Property right owners of the Sikorsky, Erickson Air-Crane Company, are looking forward to putting a number of modifications on the helicopter to further improve its efficiency.

Dual turbine enginesingle rotor helicopterwith spots for 3 crew members, minimum of two, Max Takeoff MTOW is 46, 297 lbs with an empty weight of 19,798 lbs. I spent literally 3 hours searching for the HIGE and HOGE and it isnt listed in any reference I can find. I will continue my search but dont want to post late.The main rotor is a fully articulated 6 blade rotor, and the tail is a 4 bladed tail rotor. (Aviastar, nd) The CH-54 Skycrane is an American made, twin engine, single rotor, heavy lift helicopter. The Skycrane was  mostly used by the United States Army early on, but became a staple for many heavy-lift operations later on. The Sikorsky has a unique shape which has a void in the lower fuselage area and when empty resembles a dragonfly (Infoseek, 1997).

The sikorsky was designed by the Sikorsky Aircraft Company and is named after Tarhe, a Native American chief whose nickname was the crane. (Ohio History Central Page on Tarhe) The very first flight made by this type of craft was on 9 May 1962. The total number built to date is 105. However, a variant of the CH-54 Skycrane was developed from the CH-37 Mojave and is the civil version of the Sikorsky S-64.The S-64 was used for heavy lift operations by the military.

Development of and reasoning for design
The S-64 was not the first helicopter designed as a heavy lifter. This was not even the first heavy-lift model designed by Skiorsky. The rototype S-64 first flew on 9 May 1962. This flight was followed by two further examples for evaluation by the German Armed Forces. The Germans did not place an order, but the United States Army placed an initial order for six S-64A helicopters Taylor, 1976) Seven S-64E variants were built by Sikorsky for the civil market.
 The Skycrane was actually adopted from the design of the Sikorsky S-60. A characteristic feature of the S-60 was an Autopilotautopilot which ensured stable hover and was quite advanced for its time. An additional feature of the earlier model and integrated into the S-64 was a seat which allowed the co-pilot to swivel in hisher chair in a manner that allowed the S-60 to be controlled both while facing the front and the back. The two-crew of this aircraft meant that with the S-64 loaded, the co-pilot could easily monitor it (Munson, 1968)., a concept that carries over in todays work of PF(pilot flying) and PM (Pilot monitoring). This unique was of monitoring though is noteworthy.
 Examples of S-64 loads were a medical outpost, a structure among others which can well be customized to fit in the space below the S-64s backbone. The S-60 and S-64 were designed with a skeletal fuselage, and an important portion of this was the void area for transport payload (Arnold, 2007). Some other uses for the Skycrane included parachute bombs, downed-aircraft recovery, and troopcargo transport (Leishman, 2006).

Design process specific for the Sikorsky S-64 Ch-54 Skycrane
The power packer design of the S-64 was a six-blade main rotor which was powered by two 4,050 shaft horsepower (3,020 kW)   The combined powers of these two engines enable the S-64 to lift as much as 20,000 pounds (9,072 kilograms). This was a limit however for the earlier designs. With time, the designs improved given technological developments and the newer versions with added structural rigidity could lift even up to double this weight.

Other than in the S-64, other uses of the mechanism applied in making the turboshaft engine are its applications that require continuous high power outputs. Such power is often
After new variants of the S-64 were built, it is the modular design that failed the fleet one had to constantly configure and re-configure the helicopter for every different mission that was to be undertaken. It is at this time that the S-54 was overtaken by the Boeing Chinook CH-47 which is a two rotor transportcrane hybrid (Springer, Edwin, 2001).

Still making progress
Erickson, the company which currently owns the S-64s property rights, apart from supplying newly built spares and fire-fighting kit, has also developed a more modernized Automatic Flight Control System (AFCS) for the aircraft nd other optiond. These provide precision flight control which is quite useful in the helicopters operations especially in emergency or emergency situations. It is important to note that Erickson hekicopters, the owned of the Sijorsky desigb, Erickson in marketing itself do not see its helicopters as refurbished as they are sold in a pristine condition. The company has done research on an improved S-64X which, other than featuring a modernized cockpit, also has a self-test system, composite main rotor blades, new engines possibly and a new tail rotor. Ericksons engineers are also considering the development of a passenger version as a response to suggestions from emergency response agencies which have made use of their aircranes.

Limitations and abilities of this helicopter
In order to understand the limitations of the S-64, we have to look at its abilities first given its structure. It is this same structure which works to its advantage that also works to its disadvantage. The S-64 has a rotor diameter of 21.95 m (72 ft), a length of  26.97 m (88 ft 6 in) rotors turning, height of 7.75 m (25 ft 5 in), maximum take-off weight of 21,319 kg (47,000 lb), two 3579 kW (4,800 shp) Pratt  Whitney T73-P-1 turboshaft engines, a maximum speed of 109-169 kmh (105 mph), a maximum range of 370 km (230 miles), a climb rate of 1,330 ftmin (405 mmin) and a flight ceiling of 18,330 ft (5,600 m).

However, despite all the above features of the S-64 which have added so much positivism to helicopter engineering, the S-64 has, among its limitation, a service ceiling of approximately 9,000 feet. If the S-64 flies at an altitude higher than this, the more difficult it becomes for the crew to control the helicopter due to wind turbulence at such heights (Milano, 2004).

The S-64 has a maximum speed of 109 knots and a cruise speed of 91 knots. The helicopter also has a climb rate of 1,330 ft per minute which, when further converted, becomes approximately 6.75 ms. Under its almost 90-foot length is a big space. It is in this space that the S-64 can carry loads, raising them high up hence preventing pendulum effects. This in turn results to increased stability and speeds.

Production figures, numbers in service and present uses
The first flight of the prototype S-64 was on 9 May 1962. This flight was followed by two more for evaluation purposes by the German Armed Forces. However, they did not place an order. The United States Army on its part placed an initial order for six S-64A helicopters for use by its military. And to cater for the civil market, seven S-64E variants were built by Sikorsky.

The S-64s are used especially in emergency situations. Erickson, the second manufacturer of the S-64 came up with the aircrane versions of the S-64. To achieve this, over 1,350 changes were made to the S-64s airframe, instrumentation, and payload capabilities. In case of bush fires, the aircrane is fitted with a retardant tank that can hold about 10,000 liters of water. Among other uses of the aircrane version of the S-64 are the protection of civilians, lifting of heavy construction material or critical parts of a building, for instance, the masts at the top of churches. Timber harvesters also make use of the S-64s.
The Skycrane is used for logging operations, erection of long haul power transmission towers especially in inaccessible regions to lift equipment and machineries like HVAC systems to high-rise rooftops, construction i.e.  ski lifts. It is also useful for oil exploration and drilling operations.

Comparison in terms of performance with other helicopters
Here we take a look at the Chinook helicopter in order to compare and contrast the two. Chinook helicopters look totally different as compared with the Sikorsky S-64ch-54 Skycrane. While the former has two twin rotors with one at the front and the other at the rear of the aircraft, the S-64 on its part has all its rotor blades at the top of the helicopter. On the Chinook, the one at the back is approximately 18 inches higher than the one at the front. Another distinguishing factor is in terms of carriage capacity. While the Chinook carries a maximum load of 25,000 pounds only, new models of the S-64 with far better structural rigidity can carry up to twice this load (Frawley, Gerard, 2002).

When both the Chinook and the S-64 are used as personnel carriers, the former carries 33 soldiers while the latter can carry even up to 100 of them. However, in terms of speed, the Chinook has a higher speed of 180 knots, while that of the S-64 is just but about 109 knots. The Chinook is thus more versatile as compared to the S-64. This is so because Chinooks are meant to carry supplies while Sikorskys are meant for heavier loads. This explains why Chinooks are mostly used in medical evacuations, parachute drops, among others.
However, the two have similarities in that they are used for more or less the same functions. However, in terms of number, Chinooks far outnumber the S-64 that are still in use or which were ever built because in total, there are over 1,000 Chinooks all over the world. An explanation for this might be that while the Sikorsky S-64 experiences a lot of vibrations, the Chinook features alterations to its airframe structure which has actually helped minimize vibrations. When all is said and done, we still have to acknowledge the fact that the Chinook and the Sikorsky both make use of turbo shaft engines. It is these engines that give them the power to carry such heavy loads.

We can also compare the S-64 with the S-65 which was a later development. While the initial S-64s landing gears were fixed in terms of length, the S-65 features landing gears that can be lengthened and shortened via use of hydraulics. The helicopter could appear to crouch on its load, raise the load off the ground and then transport it if need be to a more preferable take-off point (The Oredigger Issue, February 16, 2009). Such a feature was not present on the initial versions of the S-64. It is with such features of the S-65 that eclipsed the S-64, hence making the former a favorite of the military.

Sikorsky had high hopes on the S-64 but was somewhat disappointed since its most loyal client, the US Army, lost interest in it. However the company used the technology behind the S-64 to build more improved helicopters. This idea became useful in the 1960 when the US Marines were seeking for a replacement of their S-56 piston-powered helicopters. The marines were offered different machines like the Heavy Helicopter Experimental HH(X) (Swanborough, Peter, 1963). which was meant for use in assault transport, personnel transport, medical evaluation functions as well as aircraft recovery. (Vectorsite.net, 2006)Boeing Vertol offered them a modified version of the Chinook. Kaman, another helicopter producing company, offered a development of the British Fairey Rotodyne compound helicopter while Sikorsky offered an upgraded version of the S-61 which would also include among other things the dynamic system of the S-64. This was to be called the S-65. After many battles, Sikorsky won the contract in 1962. Kaman lost as the British government withdrew its support from the Rotodyne program.

Skycrane Capabilities
The  S-64 was a six-blade main rotor which was powered by two 4,050shaft horsepower Pratt and Whitney JFTD12A turbine engines. The combined powers of these two engines enable the S-64 to lift as much as 20,000 pounds, making it a true giant when it came to crane operations  lifting up to twice its own weight. Over time, these power ratings improver further. Also notable of the Skycrane, it is one of the few aircraft capable of powering out of a vortex ring state. Normally, the procedure involves forward cyclic to increase airspeed and exit the vortex area, and reduction of the collective (FAA, 2001) One interesting thing about the S-64 is the recommendation to increase power to exit the conditions, which is normally not recommended. According to most texts this will worsen the vortex ring as stated previously, but certain highly powered aircraft have the excess power to power out of such a state. One such machine is the S-64 Sikorsky Skycrane without any payload mounted to the fuselage. (Cantrell)

Statistics on the S-64
The S-60, was built as a research helicopter with joint funding by the US Navy and the Sikorsky Company. The helicopter had a long tail wheel landing gear that allowed it to straddle cargoes. The S-60 also had incorporated in it an automatic stabilization system which enabled it to hover with precision via use of inputs from a side stick controller (Goebel, 2007).

During the first production of the S-60, Sikorsky encountered some problems, one of them being the unavailability of a suitable turbo shaft power plant. However, the General Electric (GE) T64 turbo shaft and the PW JT12 turbojet were then under development and were used for the task after some modifications. This did not solve the problem fully however as the GE T64 had a front power shaft while the Sikorsky required a rear one (Apostolo, 1984). The manufacturers of T64, GE, did not feel that there was enough market to justify the development of another major variant of the T64. The JT12 on its part had a shortcoming as it would require a lot of modifications to convert it into a turbo shaft. As a solution for this problem, the United Aircraft (UA), of which both Sikorsky and PW were members, took to the task of building a turbo shaft based on the technology behind the JT12 (Hitscherberg  Daley, 2000).

The evolution of the machine. 
The first S-60 was lost in a crash in April 1961, the same period during which the first S-64 was already in the manufacturing (Swanborough  Peter, 1963). The US military, having committed to jointly fund the project, had not shown as much eagerness as expected. It is at this point that the Government of West Germany decided to evaluate the S-64 and as a result bought two of them out of the three that had been built by then. The third S-64 was however retained by Sikorsky for further developmental testing.
Goebel (2010) found though that after the evaluations, the Germans did not place an order. Instead, the US Army developed interest in the machine and placed an order for 6 S64A helicopters which were later evaluated in June 1963
   
The evaluations in 1963 further impressed the US Army and another contract for 54 more full-production CH-54 was given to Sikorsky. (Goebel, 2007), Sometime later, another order for 37 more CH-54Bs followed. The CH-54Bs were an improvement as they incorporated better PW T73-P700 engines with 4,800 SHP each and instead of single main gear wheels, they had dual wheels as well as other structural improvements to facilitate greater lift capacity. (Goebel ,2007). The building of the CH-54Bs was under the sponsorship of the US Navy, keeping in mind a scheme to deliver Polaris strategic missiles to submarines at sea. However, the CH-54Bs did not meet the navys load targets and none of those that were produced were ever bought by the navy. However, the delivery of the last of the S-64s built for the US Army was in 1972.
   
Out of the 54 CH-54s purchased by the US Army, four of them were sent to Vietnam. These were YCH-54A evaluation machines. They proved quite resourceful in the delivery of heavy equipment as well as in the retrieval of downed aircraft. Other uses of the same included clearing of helicopter landing sites in forests by dropping large bombs, a mission which was initially performed by C-130 Hercules Transport helicopters.
   
In 1968, the S-64E was introduced by Sikorsky. This was the commercial variant equivalent to the CH-54A and 10 of such were sold for use in oil drilling, construction, logging and to fight forest fires. To date, the Skycrane is still in service for forest and civil fire-fighting. For instance, there are 17 Erickson Skycranes in the Oregon State of the US which are still in service.
Old becomes new again
Initially, Erickson, which now has manufacturing rights of the Skycrane S-64, used it for construction operations until when later focus was transferred on the helicopter itself. The company then started selling refurbished S-64s. CH-54As became S-64Es, while CH-54Bs became S-64Fs which were referred to by
Erickson as aircranes (Erickson Aircrane Company, 2004)
In the late 1960s and 70s, the Chinook superseded the Tarhe. The CH54s, which were still in service, were then withdrawn from service and transferred to the Army Reserve and National Guard. However, the withdrawal from frontline units did not mark the demise of the S-60 series since as early as 1986, 71A model Tarhes were shared among some US states which included Kansas, Georgia, Mississippi, Pennsylvania and Nevada. Twenty six surviving Bs went to Alabama, Alaska, and Connecticu (Goebel, 2007). These still serve there. The machines, however badly maintained, still are the most capable machines to the army.

The number of Tarhes built for the US Army between 1964 and 1972 stood at only 97 and on 1 February 1992, Sikorsky sold the S-64 rights to Erickson Air Crane Co., which is based at Central Point Oregon. Erickson has however so far undertaken no production (Donald, 1997). Instead, it opted to sell refurbished ones as earlier stated.  

The first three aircraft, the A models produced only five helicopters, three of which were used by the US Army at Fort Benning, Georgia for testing as well as demonstration (Goebel, 2007). The other two were evaluated by the German Armed Forces. Of the A models, six were ordered by the US Army in 1963 for field testing whether they could be used to lift heavy cargo and for mobility testing in a battle field environment. Five of them were delivered with the sixth remaining at Stratford. Later in 1969, Rowan Drilling Company Inc. of Houston Texas purchased two commercial Skycranes for use in oil explorations and oil drilling in Alask (Goebel, 2007).  Later in 1969, the US Army purchased two B model Skycranes. The primary difference in the two was the better lifting and flight performance in the B-moel. Ultimately, the A model was Sikorskys first crack at the helicopter, being general in nature, while the B was designed per US Army instructions to include design improvements on the engine, gearbox, rotor head of the helicopter and its general structure. Other specifications included hot weather operating capability and altitude performance (Harding, 1990).

Civil Use
In 1969, the FAA certification for an improved Skycrane, certified for civil use as announced as the S-64E (Daley, 2000). Like its military counterpart, the S-64 civil model was designed for heavy lifting, but for firefighting, logs, air conditioners etc instead of bombs and troops
Shortly after announcing a civil model, Sikorsky made sale of one of the first S-64s to Erickson Air Crane Company of Marysville, California in 1972 for use in, among others, heavy tasks and logging operations. Later, in 1992 Erickson purchased the type certificate from Sikorsky and began development of an improved model civil Skycrane (Leishman, 2006) now known as the Erickson Skycrane, internationally (Erickson Air Crane Company, 2004)

Current History
In 2009, Erickson Air Crane leased one S-64 to the San-Diego Gas and Electric (SDGE) for 60 days for use in fighting fires. The S-64, nicknamed helitanker was then leased to the San Diego Fire Department which then had operational control over it. Erickson Air Crane currently has a fleet of 17 S-64 air crane helicopters worldwide that have been operated in at least 16 countries since 1971. (Erickson Air Crane Company, 2004). In August 1999, Erickson made available six of its helitankers to the California Department of Forestry and the US Forest Service to be used in fighting forest fires in Northern and Central California. These are just but some of the many institutions which make use of the S-64s currently owned by Erickson. At Benton Airport in California, three air cranes have also been based in the recent past to aid in fighting fires. The airport is located at the south east of Redding California. A number of S-64s are also displayed in museums, most of which are located in the United States. This totals to 17 in number.

From the initial concepts of a helicopter by Leonardo da Vinci in 1483 to the first helicopter flight in 1907 of two feet, the helicopter has journeyed a long way . (Zuelhke, 2004).  Even the more practical helicopters that showed up in later in WWII are far eclipsed by the Skycrane as it came on the scene 20 years later. Even today, the Skycrane remains a top lifter among the heavy rotorcraft remaining in service. (Zuehlke, Jeffrey, 2004)
