Abstract : The Aircraft Sound Description System (ASDS) is a method of describing aircraft noise. It has been established as the basic FAA technique for predicting community noise exposure caused by aircraft operations. This report (in four volumes) is a description of the manual and computer techniques for applying ASDS as well as a current set of noise exposure contours. This volume presents computer application procedures for ASDS. A computer program package that implements the ASDS methodology is described. The package consists of a three program sequence which performs an ASDS analysis for a given scenario, and two data reduction programs which assist in analyzing the noise exposure data produced by the analysis sequence. Instructions for preparing the required input data and running the programs are presented with illustrative examples, and the various outputs produced by the programs are described.
