Abstract

Airborne display systems provide pilots with a variety of information needed to operate aircraft. Software faults in the display system can seriously affect the operation of the aircraft, because it can provide inaccurate information to the pilot. Therefore, the software faults are identified and eliminated through ground testing and flight testing. This paper presents an analysis tool called FDR (flight data replay) for flight test of airborne display software. This tool works in real time with the mission computer of aircraft. Also, the tool reproduces the functional error conditions that appear in the display systems by applying flight test data to the display software.

항공기 시현계통은 항공기 운영에 필요한 다양한 정보를 통합하여 조종사에게 시현한다. 시현계통에서 소프트웨어 결함이 발생되면 정확하지 않은 정보가 조종사에게 시현될 수 있기 때문에 항공기의 운영에 심각한 영향을 미칠 수 있다. 따라서 시현계통의 개발 중에 지상시험과 비행시험을 통해 발생 가능한 소프트웨어 결함을 식별하고 제거하려고 노력하고 있다. 본 연구는 비행시험 자료를 이용하여 시현계통의 소프트웨어 결함 분석을 지원하는 도구인 FDR(Flight Data Replay)을 제시한다. 이 도구는 항공기 임무컴퓨터와 연동되어 실시간으로 동작한다. 그리고 시현소프트웨어에 비행시험 자료를 적용하여 시현장치에 나타나는 기능적인 오류상황을 재현한다.
