MANAGEMENT OF THE FLIGHT TRANSPORT AIRCRAFT DEPENDING ON THE FLIGHT LEVEL

Abstract

Except for the last few months of 2014, the world of the eighties of the twentieth century is in constant crisis of energy, which is a direct consequence of the steady increase in oil prices on the world market. It has forced many companies to develop new concepts of commercial aircraft to keep the highest level of passenger service by the lowest fuel consumption it shows much more cost-effective maintaining. Steady upward trend in fuel prices on the world market in the last thirty years, has forced not only small companies but also the most powerful company in the aerospace industry, such as a "General Electric", to return to research and development programs of turbo-propeller engines. In the case of aircraft DHC Dash 8 Q 400 were calculated for the change of trip fuel with changing flight levels. Completed the engineering flight preparation for the calculation of trip fuel with changing flight levels from FL160 to FL240 (flight level FL is a surface of constant atmospheric pressure e.g. 10000 ft = FL100). The airport take-off at an altitude PA = 3000 ft, and the arrival airport is at an altitude PA = 2000 ft. Based on the analysis of nine different flight levels undoubtedly come to the conclusion that regardless of the higher altitude and greater horizontal distance traveled in climbing fuel consumption is significantly lower than that flew at a much lower altitude with a much smaller horizontal distance in climbing. All the indicators that were obtained conclusively confirm the fact that the flight at high altitude allows lower fuel consumption and less time needed for the flight.
