摘　　要：民机系统级功能危害性评估(Functional Hazard Assessment,简称FHA)是指对系统功能进行系统性的综合分析过程,即依据系统功能失效状态对飞机安全性影响严重程度进行评估,从而实现对功能的等级进行识别和分类的过程,是系统顶层关键的设计过程。在分析大量相关资料和实际型号经验的基础上,得出适用于民机电传飞控系统的功能定义、功能失效状态分析和确定功能失效影响等级并对其进行确认的思路和方法,以及保证民机电传飞控系统级FHA正确性和完整性的具体可行的措施等,该方法已应用到某民机电传飞控系统级FHA的评估工作中,取得了良好的效果。Civil aircraft system functional hazard assessment refers to the process of systematic comprehensive analysis of the system function, namely according to system function failure condition to evaluate severity influence on the safety of aircraft, so as to realize the function of the level of recognition and classification process, which is the top key system design process. Based on the analysis of a large number of relevant materials and practical experience, this article gives the ideas and methods which applies to commercial fly-by-wire flight control system＇s function definition, function of failure condition, analysis and validation of the functional failure affect level, and makes sure that correctness and completeness of fly-by-wire flight control system FHA. The method has been applied to a commercial fly-by-wire flight control system of the evaluation work of FHA
