REAL-TIME AIRCRAFT NOISE PREDICTION FOR TRAJECTORY BASED ARRIVAL MANAGER

摘要

In this paper, we introduce a method for aircraft noise estimation adapted to the planning characteristics of the DLR arrival manager 4D-CARMA with significantly reduced computing times by connecting the planning algorithm with a trajectory-based aircraft noise database. Thus, it is possible to support the air traffic controller with noise abatement routes during realtime approach planning and guiding. The sound-source aircraft, the propagation medium atmosphere including actual meteorological conditions, a three dimensional model of the earth's surface, and the population distribution around an airport were taken into account for the noise propagation calculation.
