Abstract

In the end of 1990's, future free flight technology had been developed and tested in America and government established the plan for free flight until 2017. Aircraft separation assurance must be secured essentially to avoid collision between aircrafts before Free Flight comes true. Now, Civil aircraft has rules about avoidance activity with traffic collision avoidance system (TCAS) but it can't apply to light aircraft. So there is a need about alternative method to apply light-aircraft because it has space and price problem to use TCAS. In this paper, TCAS algorithm has been modified and verified by simulating with LABVIEW program under ADS-B condition to get miniaturization and weight lighting cheaply. By simulating, collision alert algorithm is analyzed and verified with collision situation proposed by ICAO, and 100% checked for performing the alert announciation on all cases by TCAS standards.

1990년대 말 미국에서는 미래 자유비행 기술개발 및 시험을 추진하였고, 이에 국내에서도 2017년까지 자유비행을 실현 할 계획을 수립하였다. 자유비행 실현을 위해서는 항공기 간 충돌의 예방을 위해 항공기 분리보증 (separation assurance)이 필수적이다. 현대 대형 민간항공기는 분리보증을 위해 충돌회피장치(TCAS; traffic collision avoidance system) 운영 및 회피 기동 규칙이 있지만 경량항공기는 비용과 공간 문제로 TCAS를 적용하기 어렵기 때문에 이에 대한 대안이 필요하다. 이에 본 논문에서는 저비용으로 경량화 및 소형화되어 구성된 ADS-B 환경 하를 가정하여 소형항공기에 적합하도록 수정하였고 LABVIEW 프로그램으로 시뮬레이션하여 시험해보았다. 시뮬레이션은 국제항공민간기구에서 제시한 항공기 충돌상황에 대하여 수행하였고, 그 결과 TCAS 기준에 따라 경보발령을 100% 수행하였음을 확인하였다.
