Optimization of RNAV Noise and Emission Abatement Departure Procedures

Abstract

In an effort to reduce the negative aspects of civil aviation on the human environment, trajectory optimization techniques have been used to reduce the single event impact of noise and gaseous pollutants of departures on communities in the vicinity of airports. For this purpose, the trajectory optimization tool NOISHHH has been adapted to design departure procedures based on Area Navigation. The new version of NOISHHH combines a noise model, an emission inventory model, a Geographic Information System and a dynamic trajectory optimization algorithm to generate flight paths with minimized noise impact and emissions. By introducing a variety of operational constraints, the resulting flight paths developed with the adapted version of NOISHHH fully comply with the regulations and guidelines applying to the design of Standard Instrument Departures and the use of Area Navigation. To illustrate the possibilities of the new version a numerical example is presented. This example is a redesign of an existing Standard Instrument Departure currently in use at Amsterdam Airport Schiphol.
