AIRPORT NOISE REDUCTION FORECAST. VOLUME II. NEF COMPUTER PROGRAM DESCRIPTION AND USER'S MANUAL

A fundamental requirement of this effort was that the noise impact of air traffic around major airports on the surrounding community should be described and that predictions of various noise abatement alternatives should be made. For this the DOT/Wyle noise exposure forecast computer program was developed. Volume 2 of the report is a description of this program. Included are brief descriptions of the calculations performed, the subroutines that perform them, and a user's guide. Also included is a complete listing of the program, in FORTRAN V. Inputs to the program are a description of the airport geometry including flight paths, aircraft noise and performance characteristics, and the aircraft fleet mix. Outputs are contours of equal value of Noise Exposure Forecasts around the airport.
