Abstract:

The effect of various departure procedures of commercial jet transport aircraft on the noise produced on the ground under the departure path are presented. Noise data at four measurement stations under the flight path of Runway 13R at John F. Kennedy International Airport, New York, were obtained from 300 aircraft departures. Four different classes of departure procedures, including those specified by current airline operating practices, are compared with the noise produced by a random set of aircraft operations where the departure procedure was unspecified. Detailed radar observations of the aircraft flights, operational information reported by pilots flying specified procedures, and the measured noise data on all flights observed were used in evaluating the various departure procedures. The study shows that implementation of a proposed departure procedure could reduce the noise levels on the ground under jet transport takeoffs by as much as 8 PNdB as compared to the noise produced by existing procedures.
