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 in tabular form a set of 239 ASDS noise exposure contours covering 51 different aircraft types. A description of the data tables and a statement of conditions and assumptions in developing the data are presented. The other volumes in the set are: Volume I, 'Overview,' Volume 2, 'Manual Application Procedures,' and Volume 4, 'Computer Application Procedures'. This document contains updated versions of the tables published in Report FAA-EQ-74-2, Volume 3, dated March 1974.
