Abstract

Airborne separation assurance is a key requirement for Free Flight Airspace operations, This paper study the feasibility of airborne separation assurance for free flight Airspaces operations by evaluating the efficiency measurement models. Three qualitatively different methods are utilized; one based Ground and Air conflict probability model, other based Dynamic Density model. the other based Direct operating cost model. The evaluation is Direct Operating Cost model and Two metrics are utilized for the efficiency measurements; airborne separation assurance performed quite well in the Free Flight evaluation; (1) 2 scenario of the conflict situations are resolved; (2) The MD-80 flight peformed separation assurance and efficiency, Not only appling for geometric method algorithm is more efficiently than potential method, but also the most efficiently geometric combined method.

항공기 분리보증은 자유비행 분리보증의 핵심요구사항이다. 본 논문에서는 자유비행 공역 효율성 측정을 위한 다양한 분리보증 및 효율성 측정 모델을 고찰하고, 자유비행 분리보증을 위한 포텐셜 필드 알고리즘과 기하학적 알고리즘, 두 가지의 충돌회피 기법을 모델링 하여 항공기 성능데이터와 두 가지 조건의 시나리오 상황에서 분리보증 해결과 운항 효율성을 측정하였다. 실험결과 자유비행 공역 하에서 기하학적 알고리즘 적용이 포텐셜 필드 알고리즘 보다 분리보증 해결, 운항 효율성 측면에서 우수하였으며, 동일한 알고리즘에서도 선회각, 속도 복합모델인 기하학적 결합 알고리즘이 더욱 효율적인 것으로 나타났다.
