An Aircraft Noise Pollution Model for Tra jectory Optimization

The mobility of our society makes effective and efficient operation of our air terminals a necessity. For this reason, landing trajectories must be optimized. One important factor in the performance index is aircraft noise received by people residing near the terminal. This paper develops a mathematical model of this noise effect so that it may be included in the performance index. The model yields the boundary on the ground inside of which the noise level is at or above 70 dB. This area can be weighted with the population density. The model compares very favorably with available data.
