摘　　要：笔者对MA600飞机电子飞行仪表系统比较器不工作告警问题进行了研究,分析了比较器不工作告警问题的主要特点,利用航电系统故障诊断体系构架中的故障树分析法对故障现象进行定性分析,梳理疑似故障源,再通过对机载系统设备离位检测、原位检和机上自检测系统(BIT)检测以及飞行时的故障现象,结合基于征兆的推理分析法排除假疑似故障,简化故障树,并根据分析结果制订故障验证方案。Theoretical study on MA600 aircraft EFIS comparator inop,analyzes the main characteristics of the comparator,the fault tree of avionics fault diagnosis system in the framework of qualitative analysis combing the suspected fault source of the fault phenomenon,through the system from the position detection,airborne equipment in situ test and machine self detection system(BIT)detection and flight fault phenomenon based on the analysis of false reasoning signs suspected for troubleshooting of simplified fault tree,and failure to develop verification scheme according to the analytical results.
