Instrument flight procedures noise prediction is an important basis of optimized land use programming and the feasibity of new-built and extened-built airport in the vicinity of an airport. This paper adopts EPNL and SEL as flight procedures noise assessment index, it combines the 4D trajectory information of flight procedures, airport type and NPD curve etc, and computes the noise value of the predicted points, and make a amendment to speed, lateral attenuation and engine installation. The establishment of flight procedures noise simulation and assessment model which based on MATLAB, analysis of the spatial and temporal distribution of approach and departure procedures of Shanghai Hongqiao Airport, and provides scientific and reliable technical basis for the optimization of airport flight program.
