Abstract

High-speed military aircraft shall be able to identify and resolve enemy threats or internal component defects with survival equipment and warning systems to minimize casualties. Warning system is divided into visual method with symbolic display and auditory method with communication equipment, which is superior in that they it has a short response time and does not cause pilot confusion by listening to simple messages. Thus, this paper suggested and evaluated effective design methods of voice/tone warning systems for military aircraft based on a life cycle perspective. Since military aircraft is safety-sensitive, priorities and three properties(Inhibitible, Interruptible, and Deactivatable) were applied to each warning to reflect criticality and urgency. As a result, we confirmed that it took 40ms to play the voice warnings, satisfying all requirements through V model-based development and testing, and improving product reliability.

고속의 군용 항공기는 인명피해 최소화를 위해 생존 장비들과 경고 시스템으로 적의 위협 또는 내부 구성품 불량을 조종사가 파악하고 해결할 수 있어야 한다. 경고 전달은 디스플레이에 심볼 전시를 통한 시각적 방법과 통신 장비의 소리를 통한 청각적 방법으로 구분되는데, 청각적 방법이 반응 시간이 짧고 단순한 메시지 청취를 통해 조종사 혼란을 유발하지 않는다는 점에서 우월하다. 이에 본 논문은 군용 항공기용 음성/톤 경고 시스템의 효과적인 설계방법을 생명주기 관점에서 제시하고 평가하였다. 안전에 민감한 군용 항공기이므로 각 경고에 우선순위와 Inhibitible, Interruptible, Deactivatable의 세 가지 속성들을 적용하여 중대성과 긴급성을 반영했다. 그 결과 음성경고 재생까지 40ms가 소요되었으며, V모델 기반 개발 및 테스트를 통해 요구도를 모두 충족했고 제품 신뢰성이 향상됨을 확인하였다.
