Abstract

Jeju International Airport has become the most delayed airport in Korea, due to increased demand in air passengers and unexpected local weather condition. Observing the demands continuously grow for a decade, the airport is expected to be saturated in the near future. As a part of effort to prepare effective and timely measure for this expected situation, airport planners seeks the annual runway capacity, i.e., the appropriate number of flight operations in a given year with tolerable delay. In practice, the FAA formula is frequently adopted for the capacity estimation. The method, however, has intrinsic issues: 1) the hourly capacity imbedded in the formula is not clearly defined and thus the estimated value is vulnerable to be subjective judgement, and 2) the formula doesn't consider aircraft delay resulted from runway congestion. In this paper, we explain a novel method for estimating the daily runway capacity and then converting to the annual capacity taking into account the aircraft delay. In this paper, average delay of aircraft was measured using microscopic air traffic simulation model. Daily capacity of the runways were analyzed based on the simulation outputs and the method to assess the yearly capacity is introduced. Using a microscopic simulation model named TAAM, we measure the average aircraft delay at various levels of flight demand, and then estimate the practical daily runway capacity. The estimated daily and annual runway capacities of Jeju airport are about 460 operations a day which is equal to 169,000 operations year. The paper discusses how to verify the simulation model, and also suggests potential enhancement of the method.

계속되는 항공수요 증가와 국지적인 기상요인으로 제주국제공항은 우리나라 공항가운데 가장 높은 항공기 지연율을 보이고 있다. 현재의 항공수요 증가추세를 감안할 때 이러한 제주국제공항의 항공기 지연현상은 앞으로 더욱 악화되어 공항의 처리능력 한계에 다다를 것으로 예상된다. 공항의 처리능력을 가늠할 수 있는 활주로의 연간용량 산정은 장래 공항계획 수립을 위한 필수적인 작업이다. 하지만 현재 실무에서는 FAA에서 제시한 산정식을 적용하여 연간용량을 산정하고 있으나, 변수에 대한 명확한 정의가 이루어지고 있지 않아 사용자의 해석에 따라 상이한 결과값이 도출될 가능성이 있으며, 항공기의 지연이 고려되지 않는다는 점에서 실무적 제약이 내재되어 있다. 이러한 실무적 한계를 개선하기 위한 방법으로, 본 논문에서는 미시적 항공교통 시뮬레이션 모형을 활용하여 활주로를 이용하는 항공기의 평균 지연시간을 측정하고, 이를 기준으로 제주국제공항 활주로의 일일용량을 분석, 최종적으로 연간용량을 산정하는 방법을 소개하였다. 또한, 시뮬레이션 모형구축 및 검증을 위한 자료수집, 분석과정과 검증결과를 설명하였다. 제주국제공항의 일일용량 및 연간용량 분석 결과, 각각 약 460회, 약 169,000회로 산정되었다.
