摘　　要：目前CCAR25部的规章要求主要针对传统机械操纵飞机,随着电传飞控系统(Fly by Wire,以下简称FBW)在现代民机上的广泛应用,在控制指令的数字信号完整性、AC 25.1309等效安全等方面产生了一些新的适航要求,以达到传统设计相同的或等效的安全水平。介绍了民机电传飞控系统安全性评估过程,然后针对电传飞控系统安全性设计特点,总结了适用的适航要求和符合性验证方法。The regulations and requirements of current CCAR 25 aim at the traditional aircrafts which use mechanical flight control system. With the widespread use of Fly-by-Wire （FBW） flight control system, some new airworthiness requirements are generated about the integrity of digital signals, and AC 25. 1309 provisions, in order to achieve the same or equivalent safety level of traditional design. This paper introduces the FBW safety assessment process of civil aircraft, and the applicable airworthiness requirements and verification methods were presented based on the features of FBW safety design.
