Abstract

The aircraft system safety assessment, which is emphasized in the development and certification of aircraft, is a systematic and comprehensive evaluation process to determine that all relevant failure conditions have been identified and that all significant combinations of failures cannot result in unacceptable hazards. As the aircraft systems become more complex and require integrated function and performance, proper safety objectives must be established and appropriate assessments are need to be accompanied. This paper has prepared to propose the efficient probabilistic analysis of failure data to evaluate the risk level over the entire aircraft lifecycle through the safety assessment and to review the considerations for aircraft certification and safety improvement.

항공기의 개발 및 인증 과정에서 중요성이 강조되고 있는 시스템 안전성 평가는 고장 또는 결함으로 인해 발생할 수 있는 위험을 사전에 식별하고, 이에 대한 영향성을 판단하여 요구되는 수준의 안전성을 확보하기 위해 적용하는 시스템 엔지니어링 기법이다. 항공기 시스템이 복잡해지고, 통합적인 기능 및 성능이 요구되면서 항공기 개발 초기부터 적절한 안전성 목표를 수립하고, 체계적인 평가를 통해 이에 대한 검증 및 후속 조치를 이행하여야 한다. 본 논문에서는 고장 데이터의 확률 분석을 수행하는 방안을 제시하여 항공기의 전체 수명주기에 걸쳐 리스크를 진단하고 효율적인 안전성 평가를 수행하기 위한 방법론을 제시하였고, 항공기 인증 및 안전성 확보를 위해 고려해야 할 사항을 제시하였다.
