中文摘要:概述了民用飞机延程运行(Extended Operations,以下简称ETOPS)的定义、适航条款、商业需求、历史,分析了双发飞机的ETOPS型号设计批准的不同取证方法(早期的ETOPS方法、服役经历法、服役经历法和早期的ETOPS方法相结合),并设置了ETOPS飞行试验的验证工作及其单发失效、座舱释压、辅助动力装置(Auxiliary Power Unit,以下简称APU)冷浸透等失效场景。为了使民用飞机可以尽快取得ETOPS批准,应结合现有的适航条款、试飞技术和方法对试飞过程进行不断优化,在同一架次上进行相似的两个模拟失效场景的飞行试验认证可以大大地节省时间和油耗。
英文摘要:This article analyzed the definition, airworthiness regulations, business requirements, and history of civil aircraft extended operations (ETOPS). Meanwhile, the article analyzed ETOPS type design approval methods(Early ETOPS Method, Service Experience Method, Combined Service Experience and Early ETOPS Method) of twin engine aircrafts in details, also the verification methods and failure scenario settings(single engine failure, cabin decompression, APU cold soak etc.)of ETOPS flight test were introduced and researched. Current flight test technologies and methods should be optimized constantly combined with the understanding of airworthiness regulations in order to help civil aircrafts get ETOPS approval as quick as possible. The article advised that two similar failure scenario settings can be conducted on the same sortie of the flight test, therefore, fuel consumption and test time can be highly saved.
