Abstract:

According to the requirement of ICAO,PBN procedures will be implemented in all China's civil airports in 2016. At present,PBN procedures are applied fully or partly in dozens of airports in our country. In addition to the influences on navigation and flight procedures,application of PBN in airports will be sure have some impacts on airport aviation noise. In this paper,the airport noise impacts differences under the condition of conventional flight procedures and PBN are computed and analyzed,moreover,the noise analysis INMsoftware and MATLAB software are applied to calculate and analyses the results. Compared with conventional flight procedures,the influenced area and shape of airport noise is different from that of noise impact caused by PBN approach,while the difference is quite small for aircraft departure. The discovery above will provide certain help to the compatibility planning of sound environment in the vicinity of airport.

Key words: airport, aviation noise, PBN
