外站经常出现翼身过热灯亮,特别是夏天,对于机龄较老的飞机几率更高(笔者曾一天遇过两起此类故障),此故障若处理不当一般都会因为停场排故导致航班延误,这无疑给航空公司的营运产生很大的困扰。本文重点阐述翼身过热探测系统构造、原理,通过案例来总结此类故障的快速处理方法,减少过站航班因此故障而延误的几率。1系统构造及原理B737飞机翼身过热探测系统由过热探测元件、控制警告电路和警告灯组成,感受由气源总管渗漏而引起的 Outside the station often appear wing body overheating lights, especially in summer, for the aircraft more likely to have older aircraft (I had met two such failures one day), this failure if not properly handled due to parking accidents led to flight Delay, which undoubtedly caused great trouble to the operation of the airline. This article focuses on the structure and principle of the wing overheating detection system, summarizes the rapid processing method of such failures through the case to reduce the probability of the delayed flight of the overpassed flight. 1 System Structure and Principle B737 aircraft wing overheating detection system consists of overheating detection components, control warning circuit and warning lights, feel the leakage caused by the gas mains
