民用飞机ETOPS重要系统适航审定研究

延程运行（ETOPS）是国际民航组织为了保证民航飞机安全飞行提出的一项运行要求，被广泛应用于洲际航线，尤其是跨洋飞行。ETOPS型号设计批准的核心是ETOPS重要系统的适航审定。对ETOPS重要系统的审定工作进行研究和讨论，分析ETOPS重要系统相关的适航条款要求，提出ETOPS重要系统确定方法和验证方法，明确有时间限...

Research on Civil Aircraft ETOPS Significant Systems Airworthiness Certification

ETOPS is an operational requirement put forward by the International Civil Aviation Organization (ICAO) in order to ensure the safe flight of civil aviation aircraft, which is widely used in intercontinental routes, especially cross ocean flight. The core of ETOPS type design approval is the airworthiness certification of ETOPS significant systems. ETOPS significant systems airworthiness certification is studied. The airworthiness requirement that refers to ETOPS significant systems is analyzed. The Methods of determining and verifying ETOPS significant systems are proposed. The approval requirement for time-limited ETOPS significant systems are analyzed. The determination method and verification method of ETOPS significant systems proposed in this paper have been applied in engineering practice, and substantive progress has been made. It has proved that the research of this paper can provide guidance for civil aircraft ETOPS type design and airworthiness certification.
