Economic Analysis On Selection Of Type Of General Trainer

China's general aviation is developing rapidly in recent years, which brings the huge demand for the pilot and in this case, the market of pilot training industry is huge in China.The using costs and benefits of general trainer which was the basic tool of flight training are important factors in the competitiveness of flight school. Therefore, how to choose a good economic general trainer is being more and more focused by operators. Nowadays, in the selection of general trainer, the main consideration is the use of the performance, the economic considerations are less in our country. How to establish scientific and reasonable selection theories and methods is becoming more and more important to flight school.First of all, combined with the use of general manager of the characteristics and operational characteristics in this paper, the costs and incomes in the service life cycle of general trainer were studied in detail. There are aircraft cost, direct and indirect operating costs, disposal costs(residual value) and incomes which are mainly refer to trainees. The direct costs contains depreciation, insurance, crew costs, fuel costs, maintenance costs and operating costs. On the basis of analyzing the composition of the direct operating costs established the calculation model of the purchase fee, depreciation, insurance, crew costs, fuel costs, maintenance costs and operating costs. Then the time value of costs and benefits is considered so that two economic evaluation indexes are used: net present value and dynamic investment recovery period and the evaluation models of the net present value and dynamic investment recovery period of general trainer in service life are presented. Finally, the investment characteristics and operational risk of general trainer were analyzed, and two risk models were established for dynamic break-even and sensitivity analysis.According to the two economic evaluation models of the net present value and dynamic investment recovery period and risk analysis models, combined with the actual situation of general trainer selection of flight school. The economic performance and operational risks of the two types of aircraft are compared and analyzed. The comparison results provide data support and scientific basis for flight school to select a good economic general trainer. Theresult of the example calculation proves the validity of the economic analysis model established above, which has a wide range of application value.
