초록
항공기는 운용환경이 상공이라는 점에서, 항공기 고장은 막대한 인적, 물적 피해를 초래할 수 있으며, 다른 운송 수단 또는 시스템에 비해서 매우 높은 안전 수준이 요구되는 특징을 갖고 있다. 항공기를 운항하기 위해서는 법에서 명시하고 있는 감항인증을 받아야 하며, 이를 통해 항공기의 비행안전성을 승인받아야 한다. 본 논문에서는 시스템 안전에 대해 군용항공기 감항인증을 기준으로 연구하였다. 군용항공기의 감항인증과 시스템 안전, 시스템 안전 절차에 대해서 정리하였으며, 다양한 민, 군 시스템 안전 표준서 및 지침에 대해서 살펴보았다. 시스템 안전 절차 관련 표준서 및 지침으로 MIL-STD-882E, SAE ARP4754A, SAE ARP4761, 14 CFR, DoDI 5000.02에 대해서 살펴보았고, 상호연관성에 대해서 연구하였다. 항공기가 부분적으로 개조되는 경우의 예를 들어 시스템 안전 업무를 분석하고, 시스템 안전프로그램 계획의 예시를 제시하였다. 군용항공기의 감항인증에 적용되는 시스템 안전 표준서인 MIL-STD-882E를 기준으로 개개의 시스템 안전 업무들을 분석하였고, 적용 항목과 비적용 항목으로 구분하였다. 시스템 안전프로그램 계획 수립은 시스템 구성의 일반적인 설계가 이루어지는 단계에서 매우 중요하며, MIL-STD-882E를 기준으로 시스템 안전프로그램 계획에서 다루어야 하는 사항의 예시를 제시하였다.
Abstract
In that the operating environment of the aircraft is in the air, aircraft failure can cause enormous human and material damage and requires a very high level of safety compared to other means of transportation or systems. In order to operate an aircraft, it must obtain the airworthiness certification specified in the law, and through this, the flight safety of the aircraft must be approved. In this paper, system safety was studied based on military aircraft airworthiness certification. Military aircraft airworthiness certification, system safety, and system safety procedures were summarized, and various civil and military system safety standards and guidelines were examined. As standards and guidelines related to system safety procedures, we looked at MIL-STD-882E, SAE ARP4754A, SAE ARP4761, 14 CFR, and DoDI 5000.02 and studied the correlation. For example, when the aircraft is partially modified, the system safety task was analyzed and examples of matters to be addressed in the system safety program plan were presented. Individual system safety tasks were analyzed based on MIL-STD-882E, a system safety standard applied to the airworthiness certification of military aircraft, and were divided into applied and non-applied items. Establishing a system safety program plan is very important at the stage where a general design of system configuration is made, and an example of the matters to be covered in the system safety program plan is presented based on MIL-STD-882E.
