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.
