典型飞机燃油量指示系统故障分析

Fuel Display Default Analysis of Integrated Avionics System Aircraft

针对某综合航电系统飞机燃油量指示故障,从油量系统的结构、原理、功能、走线、软件及配置等方面分析油量采集、信号处理和输出显示子系统,按故障树的方法重点对综合航电系统的硬件、软件及配置和线路,最后查找出故障原因并针对该机群5年来该组件的故障次数及原因进行了统计和分析。

According to a load of integrated avionics system of the aircraft left the tank fuel quantity indicating fault, indicating system from the type fuel and the intersection of integrated avionics system in the structure, principle, function, walk the line, software and configuration were analyzed. Making troubleshooting procedures focus on examination of integrated avionics system hardware, the software and configuration and the line according to the easy first principle. The fault of electronic components engine trouble was foubd out. The statistics and analysis for the cluster 5 years the component failure number and the reasons were made.
