Abstract:

This report describes a procedure for generating noise contours around general aviation airports using three units of noise exposure composite noise rating CNR, noise exposure forecast NEF, and daynight levels LDN. The procedure is to determine the number of annual operations at an airport, and to apply a weighting to this number to account for such effects as multi-engine and nighttime operations propeller and jet operations are considered separately. A series of noise contour maps are provided in the report for a wide range of numbers of annual operations, based on standard flight tracks. The appropriate maps should be selected taking account of mixed propeller and jet operations, multiple runway usage, etc. enlarged and combined by logarithmic addition of noise exposure levels to produce an overall set of noise contours for the airport.
