본 논문은 기록된 항적 데이터를 이용하여 혼잡한 공항의 비행 절차별 위험도를 분석하는 방법론을 제시하고, ADS-B (automatic dependent surveillance-broadcast) 데이터를 기반으로 재생성된 100일 치의 항적 데이터를 사용하여 인천국제공항과 김포국제공항의 비행 절차별 위험도를 분석한 결과를 보여준다. 위험도 분석은 DWC (detect and void well clear) 를 이용하였으며, 이를 통해 비행 절차별로 가장 높은 위험도가 나타나는 구간과 위험 발생이 잦은 구간을 평가하였다. 그 결과, 인천국제공항의 표준계기출발절차 중 RNAV BOPTA 1L의 SI712 - RANOS Fix 구간에서 가장 높은 위험도가 나타났으며, 표준계기도착절차 중에서는 RNAV GUKDO 1N에서는 SI947-DANAN Fix 구간에서 가장 높은 위험도가 나타났다. 또한 김포국제공항의 표준계기출발절차 중에서는 RNAV BULTI 1X의 SS726 - SS727 Fix, 표준계기도착절차 중에서는 RNAV OLMEN 1D의 KAKSO - KALMA Fix 구간에서 가장 높은 위험도가 나타났다.

In response to the recent surge in aviation demand, major airports and aviation authorities continue to make efforts to formulate arrival and approach procedures that take into account efficient aircraft separation, noise and environmental issues of carbon (CO2) emissions. In order to ensure efficient traffic control and environmental issues, as a result, a new concept Trombone, Point Merge, etc. have been introduced and widely used in the domestic airspace. However, these new concept procedures which do not properly reflect the characteristics of the aircraft operation performance and the FMS vertical descent guidance hinder flight efficiency as well as bring in turn negative factors such as level-off flight and the use of drag device at the busiest phase of the flight descent operation, like the Continuous Descent Operation (CDO). Accordingly, throughout modification the current Standard Terminal Arrival Route (STAR) and Instrument Approach Procedure(IAP) that reflect the aircraft descent performance and the FMS guidance, the flight operation safety and efficiency is expected to be improved eventually. We herewith analyze and propose the way of improving flight efficiency in the arrival operation procedure by supplementary modification which consequently contribute to the aviation industry international competitiveness.

In response to the recent surge in aviation demand, major airport and aviation authorities continue to make efforts to formulate arrival procedures that take into account efficient aircraft separation, noise and environmental issues related to carbon (CO₂) emissions. In order to ensure efficient traffic control and environmental issues, as a result, a new concept Trombone, Point Merge, etc. have been introduced and widely used. However, these new concept incisions are becoming a factor that hinders operational efficiency and stability due to the restricted domestic airspace such as military airspace and excessive constraints of altitude, speed, etc. which do not reflect the concept of continuous descent operation and eventually needs to be modified to make continuous descent operation as feasible as possible. We herewith analyze and propose the way of improving flight safety and efficiency in the arrival operation procedure by supplementary modification which consequently contribute to the aviation industry international competitiveness.

The continuous increase in air traffic emphasizes the importance of capacity calculation. Research on the calculation method of Terminal Control Area (TMA) capacity has been treated as a partial aspect of the airspace sector capacity or has been limitedly studied. This study aims to propose a mathematical model for calculating TMA capacity, taking into account the Standard Terminal Arrival Route (STAR), separation standards, TMA entry speed, and runway threshold passing speed. The proposed model has the advantage of being able to calculate the instantaneous arrival capacity, which has not been noted in previous studies, along with the throughput. Additionally, it is meaningful as the model can easily calculate the arrival capacity of the TMA considering airport construction, runway expansion, or new procedures.
