Airplane technology is undergoing several exciting developments, particularly in avionics, material composites, and design tool capabilities, and, though there are many studies conducted on subsets of airplane technology, market, and economic parameters, few exist in forecasting new commercial aircraft model introduction. In fact, existing research indicates the difficulty in quantitatively forecasting commercial airplanes due in part to the complexity and quantity of exogenous factors which feed into commercial airplane introduction decisions. This paper seeks to address this gap.

The analysis is based on a literature review, supplemented by a collection of secondary data. The study then focuses on applying three technology forecasting techniques: multiple regression; linear regression; and the Pearl growth curve.

The results provide a valid model for multiple regression and linear regression on range and composite material percentage for use in commercial airplane forecasting. However, growth curve analysis, comparatively, appears to provide the most intriguing and flexible forecast outlook in alignment with industry dynamics.

Research implications include a caution for forecasters in support of the difficulty of commercial aircraft forecasting due in part to the quantity of exogenous factors, particularly compared with a related industry, military aircraft. Future work could include: utilizing other forecasting techniques that allow for greater numbers of forecast factors, additional future models, additional range aircraft and/or analyzing the impact that competing transportation modes in mid‐range aircraft could have on long‐range aircraft introduction.

The study provides value in extending a previous descriptive paper on airplane parameters. Additionally, it appears to be one of the first quantitative examples supporting previous research indicating the complexity of forecasting airplane new product introduction, but it overcomes some of this complexity by providing a valid model for forecasting with range and composite material percentage as inputs.

COMMERCIAL air transport is a major growth industry. This growth, although fundamentally due to economic and political trends, has been greatly accelerated by the technological advance of aero engines and airframes.

At the dawn of the twenty-first century, Boeing and Airbus, the leading manufacturers of large aircraft, were locked in a battle for market share that drove down prices for their new planes. At about the same time, the two industry heavyweights began developing new aircraft families to address the future market needs they each projected.

Aircraft take many years to develop, so by the time the new planes made their inaugural flights, significant changes had occurred in the global environment. First, emerging economies in the Asia-Pacific region and elsewhere were growing rapidly, spawning immediate and long-term demand for more aircraft. At the same time, changes to the market for air travel had created opportunities for new products. These opportunities had not gone unnoticed by potential new entrants, which were positioning themselves to compete against the market leaders.

In October 2007, the Airbus superjumbo A380 made its first flight. The A380 carried more passengers than any other plane in history and had been touted as a solution to increased congestion at global mega-hub airports. Four years later the Boeing 787, a smaller long-range aircraft, was launched to service secondary cities in a point-to-point network.

The case provides students with an opportunity to analyze the profit potential of the global aircraft manufacturing industry in 2002 and in 2011. Students can also identify the actions of participants that weakened or intensified the pressure on profits within the industry.

Boeing has been a pioneer in the utilization of strategic alliances with the Japanese in the design and production of aircraft. This strategy has been driven by the escalating costs of airframe and engine design and manufacture, and the significant competition of Airbus as well as domestic competitors in the global aircraft market. Boeing's alliances with Japan have worked well with several families of aircraft and appear to have produced a loyal customer; however, there have been sharp criticisms of Boeing for the closeness of its association with Japan. These criticisms have largely been aimed at the danger posed by unintentional and unavoidable transfer of aerospace technology. This paper examines the history of Boeing's Japanese coalitions, the benefits, and the dangers posed by Boeing's continued aerospace partnership with one of America's largest economic foes.

This paper aims to review national aeronautics and space administration (NASA’s) broad investments in electrified aircraft propulsion (EAP). NASA investments are guided by an assessment of potential market impacts, technical key performance parameters, and technology readiness attained through a combination of studies, enabling fundamental research and flight research.

The impact of EAP varies by market and NASA is considering three markets as follows: national/international, on-demand mobility and short-haul regional air transport. Technical advances in key areas have been made that indicate EAP is a viable technology. Flight research is underway to demonstrate integrated solutions and inform standards and certification processes.

A key finding is that sufficient technical advances in key areas have been made, which indicate EAP is a viable technology for aircraft. Significant progress has been made to reduce EAP adoption barriers and further work is needed to transition the technology to a commercial product and improve the technology, so it is applicable to large transonic aircraft.

This paper will review the activities of the hybrid gas-electric subproject of the Advanced Air Transport Technology Project, the Revolutionary Vertical Lift Technology Project and the X-57 Flight Demonstration Project, and discuss the potential EAP benefits for commercial and military applications. This paper focuses on the vehicle-related activities, however, there are related NASA activities in air space management and vehicle autonomy activities, as well as a breakthrough technology project called the Convergent Aeronautics Solutions Project. The target audience is people interested in EAP.

This paper aims to assess the impact of electrifying the environmental control system (ECS) and ice protection system (IPS), the primary pneumatic system consumers in a conventional commercial transport aircraft, on aircraft weight, range, and fuel consumption.

The case study was carried out on Airbus A321-200 aircraft. Design, modelling and analysis processes were carried out on Pacelab SysArc software. Conventional and electrical ECS and IPS architectures were modelled and analysed considering different temperature profiles.

The simulation results have shown that the aircraft model with ±270 VDC ECS and IPS architecture is lighter, has a more extended range and has less relative fuel consumption. In addition, the simulation results showed that the maximum range and relative fuel economy of all three aircraft models increased slightly as the temperature increased.

Considering the findings in this paper, it is seen that the electrification of the conventional pneumatic system in aircraft has positive contributions in terms of weight, power consumption and fuel consumption.

The positive contributions in terms of weight, power consumption and fuel consumption in aircraft will be direct environmental and economic contributions.

Apart from the conventional ECS and IPS of the aircraft, two electrical architectures, 230 VAC and ±270 VDC, were modelled and analysed. To see the effects of the three models created in different temperature profiles, analyses were done for cold day, ISA standard day and hot day temperature profiles.

The CEO of Embraer, reflects on his company's dramatic ascent to its position as the world's leading regional aircraft manufacturer. Since becoming a private company, Embraer had successfully introduced seven commercial aircraft models to the market, including its latest, the 118-seat EMBRAER 195. Now, he is concerned because Embraer does not know what to expect from Bombardier, Boeing, and Airbus regarding their competitive response to his company's recent attacks on the commercial aircraft market. How would they respond to Embraer's successful launch of its recent family of jets? Would Bombardier really follow through with its launch of the CSeries? Would Airbus and Boeing perceive the latest attacks by Embraer and Bombardier as attacks on its own family of jets? Most importantly, given Embraer's expectations of rivals' future competitive moves, what should it do next to protect its position and influence its competitors' actions?

Examines the dramatic change of commercial aircraft manufacturing from the traditional product development method dominated by military heritage and product superiority at the expense of cost and time‐to‐market. Losses by airlines in the 1990s highlighted economic difficulties and left airlines unable to grow and purchase new commercial aircraft. Describes the challenge faced by British Aerospace Regional Aircraft to develop a business‐wide simultaneous engineering programme to improve the managing of engineering products; outlines in detail the goal‐directed product management approach used and describes why this approach was successful.

The purpose of this study is to present the pollutant gas produced by hydrocarbons (HC), carbon monoxide (CO) and nitrogen oxides (NO_x) and the quantity of fuel burned from commercial aircraft at Ordu-Giresun International Airport, Turkey during the landing and take-off (LTO) cycles in 2017.

The flight data recorded by the General Directorate of State Airports Authority and the aircraft engine emission data from International Civil Aviation Organization (ICAO) Engine Exhaust Emission Databank were used for calculation. The aircraft and engine types used by the airlines for flight at Ordu-Giresun International Airport were determined. To evaluate the effect of taxi time on emission amounts, analysis and evaluations were made by taking different taxi times into consideration.

As a result of the emission analysis, the amount of fuel consumed by the aircraft were calculated as 6,551.52 t/y, and the emission amounts for CO, HC and NO_x were estimated as 66.81, 4.20 and 79.97 t/y, respectively.

This study is aimed to reveal the effect and contribution of taxi time on the emitted emission at the airport during the LTO phase of the aircraft.

This study helps aviation authorities explain the importance of developing procedures that ensure the delivery of aircraft to flights in minimum time by raising awareness of the impact of taxi time on emitted emissions, and contributes to the determination of an aircraft emission inventory at Ordu-Giresun International Airport.
