Flight simulation investigations for the problem of flyability of noise optimal approach and takeoff paths
Abstract
Noise reduction during takeoff and landing of the A 300 B Airbus was studied using flight simulation. Operational aspects such as flyability and safety were emphasized. The investigations were limited to aircraft control in the vertical path plane, since the extension to the horizontal path control can only be made for a real airport and its surroundings. Noise emission parameters included noise frequency, direction and thrust dependence of propulsion system noise emission, aircraft spatial position, air damping as a function of noise frequency, air temperature and relative humidity as a function of flight height, and soil damping. The results show that reductions of the noise in the neighborhood of airports are possible, compared to the usual takeoff and landing methods (IATA steep takeoff method, low drag low power approach method).
