某型飞机多功能显示器偶发黑屏故障分析

Analysis of Occasional Black Screen Fault in Multi functional Display of a Certain Aircraft

对某型飞机外场飞行中偶发多功能显示器黑屏故障进行研究分析,通过现场检查、现象分析、电路分析和失效分析确认故障诱因,并提出建议及预防措施,为外场类似故障提供理论支撑。

This paper studies and analyzes the occasional black screen failure of multi-function display in the flight of a certain type of aircraft in the field,confirms the cause of the failure through field inspection,phenomenon analysis,circuit analysis and failure analysis,and puts forward suggestions and preventive measures to provide theoretical support for similar failures in the field.
