Ulsan Airport cannot operate precision instrument approach procedures from the south direction (Runway 18) due to obstacles. Even non-precision instrument approach procedures have higher approach angles and minimum descent altitudes (MDA) compared to other airports, which can pose safety risks for pilots following the flight procedures. Recently, since the introduction of SBAS-based satellite navigation flight procedures in Korea, Ulsan Airport is expected to experience improvements, including reduced offsets and lower minimum descent altitudes in its existing flight procedures. During the design process of new flight procedure routes, a comprehensive analysis of noise differences from existing routes and the noise impact on new areas is necessary. Therefore, this study aims to present the changes in aircraft noise resulting from the implementation of new flight procedures using the Aviation Environmental Design Tool (AEDT)
