Abstract

With the operation of the Korean satellite-based augmentation System (KASS), it has become possible to develop and implement localizer performance with vertical guidance (LPV) instrument approach procedures. In this study, we developed an LPV procedure for Runway 18 at Ulsan Airport, where the installation of an instrument landing system (ILS) is unable due to obstacles, and examined the potential reduction in flight cancellations. The study results suggest that, when developing an LPV instrument approach procedure, the decision altitude would be 380 feet, and the visibility minimum would be 1,200 meters. Consequently, it is expected that flight cancellations for Runway 18, based on 2023 cancellation data, could be reduced by 92% under the given visibility and ceiling conditions if LPV instrument approach procedure is developed. Therefore, the development and operation of the LPV instrument approach procedure for Runway 18 at Ulsan Airport is deemed essential.

한국형 위성기반보정시스템(KASS)의 운영으로 LPV (localizer performance with vertical guidance) 계기접근절차를 개발 및 운영할 수 있게 되었다. 본 연구에서는 장애물로 인해 ILS 설치가 어려운 울산공항의 18 활주로를 대상으로 하여 LPV 절차를 개발해보고 결항 감소 효과를 연구하였다. 연구 결과 LPV 계기접근절차 개발시 결심고도는 380 ft, 시정제한치는 1,200 m가 예상된다. 이에 따라 LPV 계기접근 개발시 18 방향 활주로 이용시 시정과 운고에 따른 결항은 2023년 결항횟수 기준 92%가 감소할 것으로 예상되므로 울산공항 활주로 18 LPV 계기접근절차의 개발 및 운영은 반드시 필요해보인다.
