This report contains an update and revision of the estimated noise impact of airport jet air carrier operations in the years 1975 and 2000. These estimates are based on the current takeoff flight procedures, the 1979 FAA fleet forecast, and current definitions of new technology aircraft. They do not assume additional regulatory actions, either in aircraft noise certification or in airport operations, nor do they assume additional noise control efforts on the part of individual airports. These results are based largely on the methodology and data contained in a prior study except for updating certain basic information in that study from 1975 to 1979 and revising a part of the methodology for estimating population impacted.
