항공기 소음저감 실효성 증진방안 - 김해국제공항을 중심으로

The differences in noise effects between standard flight paths and actual flight tracks notified in AIP(Aeronautical information publication) of Gimhae Airport were compared and analyzed. In order to verify the effect of noise reduction according to flight path selection, INM, which is a commercial program used to draw an aircraft noise map, was used to predict noise impact. In order to improve consistency, this study tried to minimize the error by comparison with the data of the noise monitoring network. The differences in noise effects between standard flight paths and actual flight tracks notified in AIP of Gimhae Airport were compared and analyzed. Initially, it was expected that the irregular actual flight tracks pattern would have a larger area of noise damage than the single standard flight path(listed in AIP) which has an even and regular pattern. However, the result of prediction through the INM program simulation showed that the noise impact(surface area, number of houses, etc.) by a single standard flight path was greater.

This study explored measures to reduce noise applicable to Gimhae international airport centering on densely packed housing areas. Especially, as for measures to relieve noise damage on the densely packed housing areas in Gimhae-si, the noise reduction effect is expected to be doubled if the west runway (36L/18R) is used as the preferred runway for the 36 direction takeoff, as well as if the flight bypasses the densely packed housing areas by means of sophisticated navigation using the area navigation (RNAV) procedure based on performance-based navigation (PBN). Takeoff toward the south connects the flight path to the South Sea which has comparatively low noise impact, relieving noise damage on the densely packed housing areas (apartment complexes in Naeoe-dong of Gimhae-si, etc.) near the northern end of the runway. The operation of the runway displaced threshold is currently being implemented on the west runway (36L/18R) of Gimhae international airport. It has been found that swing landing in spring and summer when the wind blows from the south has a noise reduction effect on the noise sensitive areas at the side and end of the west runway (Gangdong-dong and Jukdong-dong of Gangseo-gu and Buram-dong of Gimhae-si, etc.).
