A comparison of noise abatement procedures using radar data and simulated flight trajectories

Abstract

The increasing number of aircraft movements has caused aircraft noise to be perceived as a serious environmental problem. In order to reduce aircraft noise several noise optimized approach procedures, take-off procedures, and corresponding flight paths have been developed. In addition, several measures like night flight restrictions, noise preferential runways, bigger airplanes, quieter engines and noise contingent contributes have also been proposed for the reduction of aircraft noise. This paper discusses different sources of flight trajectories that can be used for noise calculation and analyses their advantages and disadvantages. On this basis selected evaluation results of noise abatement procedures developed in a German government study are presented and discussed.
