Abstract

According to the International Air Transport Association (IATA), 61% of the accidents occurred during the approach and landing phase of the flight, with 16% of the accidents caused by unstable access of the commercial aircraft. It was identified that the pilot's unstable approach and poor manipulation of correction led to accidents by continuing the excessive approach without go-around manuever. The causes of unstable access may vary, including airport approach procedures, pilot error, misplanning, workload, ATC (Air Traffic Contol) congestion, etc. In this study, we use the flight data analysis system to select domestic case airports and aircraft type where unstable approach events occur repeatedly. Through flight data analysis, including main events, airport approach procedures, pilot operations, as well as various environmental factors such as weather and geographical conditions at the airport. It aims to identify and eliminate the tendency of unstable approach events and the causes and risks of them to derive implications for mitigating unstable approach events and for developing navigation safety measures.

IATA (International Air Transport Assosiation)의 운송용 항공기 사고 집계에 의하면, 사고 건의 61%가 비행의 접근 및 착륙단계에서 발생 되었으며, 이중 항공기의 불안정한 접근으로 인한 사고가 16%인 것으로 파악되었다. 이는 조종사의 불안정한 접근 및 수정 조작 미흡에 따른 복행을 시행하지 않고, 무리하게 접근을 지속하여 사고로 이어진 것으로 식별되었다. 불안정 접근의 원인으로는 공항의 접근 절차, 조종사의 실수, 잘못된 계획, 업무 부하 (workload), ATC (Air Traffic Control) 혼잡 등 다양하게 있을 수 있다. 본 연구에서는 비행 데이터 분석 시스템을 활용하여, 불안정 접근 이벤트가 반복해서 발생하는 국내의 사례 공항과 기종을 선정하여, 주요 발생 이벤트, 공항 접근 절차, 조종사의 조작 뿐만이 아니라 공항의 기상, 지리적 여건 등 다양한 환경적 요인을 포함한 비행 데이터 분석을 통해 불안정 접근 이벤트의 경향성과 발생 원인 및 위험 요소를 식별하고 제거하여 불안정 접근 이벤트의 경감조치 및 항행 안전 증진 방안 마련의 시사점을 도출하고자 한다.
