| 摘 要： | 2011年底中国民航局新发布的CCAR25.1709对于电气线路互联系统（ Electrical Wiring Interconnection Sys-tem,简称EWIS）安全性提出了更完全和结构化的评估要求。分析了原规章条款25.1309对于EWIS安全性评估的不足和对新规章条款25.1709的要求及其理解,并结合具体的民用飞机设计经验,分别从EWIS失效产生的功能性和物理性两方面安全性影响,探讨了EWIS对于25.1709的符合性设计和分析的过程与方法。

| Abstract: | CCAR25.1709 is issued by CAAC at the end of 2011, which requires a thorough and structured analysis of EWIS safety. This paper introduces the inadequacies of original 25.1309 in relation to EWIS safety assessments and the understanding of new 25.1709 requirements. The compliance of 25.1709 and the EWIS development process are discussed from the safety effects both EWIS functional failure and physical failure. |
