Methods for analyzing the economic activity of airlines and forecasting the prerequisites for bankruptcy of airlines is becoming an important task for development of the industry. In past years, there were examples of a sound negative experience related to bankruptcy of airlines. At the same time, the main volume indicators of the airlines concerned had got positive dynamics shortly before the bankruptcy and were considered by BCG matrix as evident «stars» in terms of growth in production volumes and in the share of the air transportation market. In Russia that was the case of Sibir airlines which in 2007–2008 barely avoided bankruptcy, as well as of Transaero Airlines that has left the air transportation market forever. The first lowcost airlines, Skyexpress and Avianova, went bankrupt amid high growth in the number of passengers transported. The task of the research was to create a model that allows to simulate the situation associated with the airline overcoming the so-called «second break-even point». To forecast the possible time period for the airline to receive an operating loss against the background of growing volume indicators, production and financial indicators of one of the leading Russian airlines were used. The method of research is modelling of volume and financial indicators of the airline activity. The model is proposed to be built not on the study of future changes in the growth of volume and financial indicators, but on the study of dynamics of the rate of change of those indicators. The study is based on the fact that the dynamics of air transportation has a cyclical basis, which is invisible when directly analyzing changes in production and financial indicators, and which is on the contrary clearly visible when studying the dynamics of the rates of those indicators, which makes it possible to simulate a situation when the airline will have an operational loss in the future.

Air transportation is a necessity for regional economic activities, where passengers will have an important role for the survival of the aviation world. Knowing what factors are the most influential in the movement of prospective passengers is important to know the future of the aviation world, especially for the Special Region of Yogyakarta. So in this study designed a system that can be used to solve these problems. Where this system uses eight variables, namely the number of passengers, the number of residents, the number of hotels, the number of universities, the number of students, the number of hospitals, the number of workers, and the number of companies.

As global air travel expands rapidly to meet demand generated by economic growth, it is essential to continue to improve the efficiency of air transportation to reduce its carbon emissions and address concerns about climate change. Future transports must be ‘cleaner’ and designed to include technologies that will continue to lower engine emissions and reduce community noise. The use of computational fluid dynamics (CFD) will be critical to enable the design of these new concepts. In general, the ability to simulate aerodynamic and reactive flows using CFD has progressed rapidly during the past several decades and has fundamentally changed the aerospace design process. Advanced simulation capabilities not only enable reductions in ground-based and flight-testing requirements, but also provide added physical insight, and enable superior designs at reduced cost and risk. In spite of considerable success, reliable use of CFD has remained confined to a small region of the operating envelope due, in part, to the inability of current methods to reliably predict turbulent, separated flows. Fortunately, the advent of much more powerful computing platforms provides an opportunity to overcome a number of these challenges. This paper summarizes the findings and recommendations from a recent NASA-funded study that provides a vision for CFD in the year 2030, including an assessment of critical technology gaps and needed development, and identifies the key CFD technology advancements that will enable the design and development of much cleaner aircraft in the future.

The Future

The year 1925 marked the beginning of air transportation as an industry. Since then it has advanced through successive stages of growth and development until to-day, as the author believes, air transport is in the state of transition between the pioneering period and that of mature growth. Airway mileage by scheduled air transports in the United States has increased from a total of 2,000,000 miles flown in 1926 to 90,000,000 in 1939. Air passenger-miles in 1938 aggregated 600,000,000. In this paper the author reviews the technical developments in aircraft and improvements in airway operation which have made possible this phenomenal growth. Every phase of this development which has played a part in the successful and safe operation of the airway systems of the present day is treated comprehensively in order that an understanding may be gained of the future possibilities of air transport and the lines along which it will advance.

Determining how the controller (or air navigation service provider) of the future will function in tomorrow's Next Generation Air Transportation System (NextGen) will require an understanding of the existing literature. In this chapter, after an analysis of the controller's job, we focus on technology, which is an important factor in air traffic control (ATC) today and will become increasingly so in NextGen. We then turn to workload and the extent to which it can be predicted. From human-technology interaction and workload, we move to the multiple facets of cognition thought to underlie these and other aspects of the controller's job. Beyond individual cognition, we review collaboration among controllers and discuss both synchronous cooperation and the cooperative shift change. As we move up the system, we look at error, risk, and safety. Finally, we consider the work on controller selection, covering both “select-in” (KSAOs) and “select-out” (e.g., medical and suitability) factors. For NextGen to be successful, human factors researchers must determine from today's research how the human operator can best function to provide ATC services in the future.
