Optimization Of Departure Flight Procedures Based On Noise Assessment

At present,the number and scale of civil aviation transportation airports continue to increase,and the transportation volume has increased sharply.While the airport brings convenience to people,it also brings noise pollution.Scientifically reducing airport noise pollution is an issue of great concern all over the world.This article introduces the impact and harm of airport aviation noise on noise-sensitive areas,outlines the current situation and progress of domestic and foreign research on airport noise,analyzes the noise evaluation indicators used by domestic and foreign airports,and elaborates the calculation principle of airport noise in detail And process.Based on the Chinese standard "Measurement Method of Aircraft Noise Around Airports"(GB9661-88),"Environmental Standards for Aircraft Noise Around Airports"(GB9660-88)and "Recommended Calculation Methods for Noise Contours Around Airports"(DOC9911)published by the International Civil Aviation Organization As a basis,comprehensive consideration of basic theories of flight procedures and flight performance,etc.,establish an airport noise assessment model.Combining with the actual operating conditions of a domestic airport,study the effect of noise generated by the aircraft during take-off and departure.Obtain departure track data through aircraft performance software,use MATLAB software to program for noise calculation,and use Aviation Environmental Design Tool to verify the correctness of noise contours.Calculate and analyze the noise impact data generated by traditional departure procedures,PBN(Performance Based Navigation)departure procedures,and Noise Abatement Departure Procedure,through the shape and area of noise contours for different flight procedures Demonstration and evaluation of noise changes in length,length and sensitive areas,comprehensive consideration of noise avoidance and obstacle clearance requirements,and proposed an optimization plan for departure flight procedures based on noise evaluation,thereby reducing noise pollution and mitigating the impact of noise on sensitive areas.
