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 the manual procedure for developing an Aircraft Sound Description System (ASDS) application in a step-by-step fashion. This procedure develops the aircraft noise exposure values and the 'Situation Index.' Data forms and pictorial layouts are used to illustrate the procedure. A sample application is presented to explain the details of each step. (Author)
