Abstract

Due to the rapid increase in air traffic worldwide, ICAO has replaced the existing navigation equipment with equipment based on satellite navigation. As a part of that work, ICAO was planning to replace conventional takeoff and landing service using ILS with GBAS. Unlike ILS, GBAS which uses precision approach service inducing aircraft to airport and satellite based augmentation system providing precise position information service surrounding airport is capable of providing a required performance by only a system, regardless of the number of systems, and has an advantage that it is possible curved approach. In this paper, fuel reduction of ILS approach procedures and GBAS curved approach procedures is estimated and determined by flight test in Taean Airport.

전 세계적으로 급속하게 증가하는 항공교통량으로 인해 ICAO는 기존의 항행장비를 위성항법 기반으로 대체해 나가고 있으며, 이의 일환으로 기존의 ILS를 이용한 이착륙 서비스를 GBAS 로 대체할 계획을 수립 하였다. GBAS는 활주로까지 항공기를 유도하는 정밀 접근 서비스와 공항 주위의 정밀위치정보 서비스를 제공하는 위성항법 보강시스템을 이용하여 ILS와 달리 한 개의 시스템으로 활주로의 수에 관계없이 요구 성능을 제공할 수 있으며 curved approach가 가능하다는 장점을 보유하고 있다. 본 논문에서는 태안비행장 비행시험을 통한 ILS접근 절차와 GBAS curved approach절차를 비교하여 비행시간 단축 및 연료 감소효과를 분석하였으며 실제 비행시험을 통하여 이를 측정 확인 하였다.
