Abstract

Jeju International Airport is experiencing heavy congestion and delays due to the rapid increase of passengers. As of 2019, delays occurred in 24,052 aircraft, which account for over 14% of all flights operated. This delay rate is about 1.5 times higher than the average delay rate of 9% at domestic airports. The factors which bring delays at Jeju International Airport may include saturation of runway capacity, poor weather conditions, and limitations in facility layout. However, there are insufficient empirical studies on how these factors have affected aircraft delays. This study analyzed the effects of airport operation characteristics, weather conditions, and aircraft operation characteristics on aircraft delay using tower-log data of Jeju International Airport and Aeronautical Climatological Statistics of Jeju International Airport of Aviation Meteorological Office. The result of the analysis shows, aircraft movements per day, aircraft movements per hour, time of day, wind, route and aircraft occupancy rate have a statistically significant effect on aircraft delay, and the relative importance of variables appeared in the order of aircraft movements per day, wind, visual, and aircraft occupancy rate. In addition, these variables were analyzed to have a statistically significant effect on the delay time of aircraft. The results of this research are expected to be used as a basic data for aircraft delay management in airport planning and operation, and contribute to improve methodology of the feasibility study for airport projects.

최근 제주국제공항은 이용객 증가에 따른 공항의 혼잡 및 항공기 지연이 극심해지고 있는 추세이다. 2019년 기준 전체 운항편의 약 14.1%에 해당하는 24,052편의 항공기에서 지연이 발생하였으며, 이는 전국공항의 평균 지연율인 9% 대비 약 1.5배 높은 수준이다. 특히 출발항공기 지연율은 국내공항 출발항공기 평균인 9.91%의 약 2.2배 수준인 21.3%로 제주국제공항의 지연은 매우 심각한 수준이다. 이러한 지연 증가의 원인으로는 활주로 용량 포화, 불량한 기상여건, 시설배치 한계 등이 언급되고 있으나 실제로 이러한 요인들이 항공기 지연 여부에 미치는 영향에 대한 실증적 연구는 부족한 실정이다. 이에 본 연구에서는 2019년 1년간 제주국제공항의 항공기 운항일지(Tower-log) 자료와 항공기상청의 제주국제공항 공항기후통계 자료를 활용하여 공항의 운영특성(일운항횟수, 시간당운항횟수 등)과 각종 기상현상(풍속, 시정, 강우량 등), 항공기 운항 특성(운항노선, 항공기 탑승율 등)이 항공기의 지연 여부 및 지연시간에 미치는 영향을 분석하였다. 분석 결과, 일운항횟수, 시간당 운항횟수, 운항시간대, 강수량, 풍속, 운항노선, 항공기 탑승률과 같은 다양한 변수가 항공기 지연에 통계적으로 유의한 영향을 미치는 것으로 나타났으며, 변수의 상대적 중요성은 일운항횟수, 풍속, 시정, 항공기 탑승률의 순으로 확인되었다. 또한 이러한 변수들은 항공기의 지연시간에도 통계적으로 유의한 영향을 미치는 것으로 분석되었다. 본 연구의 결과는 공항의 계획 수립 및 운영단계에서 항공기 지연 관리, 그리고 공항부문 사업의 타당성조사 방법론 개선 등에 기초 자료로 활용될 수 있을 것이다.
