Cessna 172R基本型飞机电瓶电量耗尽空中断电故障分析及解决措施

在我院Ces sna1 7 2R基本型飞机的飞行训练中,近两年已先后发生5起空中供电中断、通讯失效、地面不能跟踪飞机目标的不安全飞行故障现象。这不仅增加了飞行员的心理压力,对飞行安全造成较大威胁,也严重影响了1 7 2R基本型机队的正常飞行计划。本文在分析电瓶电量耗尽、飞机空中供电中断故障原因的基础上,提出了加装低电压音响警告系统这一简单、可行的解决方案,并于2009年5月完成了我院所有20架1 72R基本型飞机加装低电压音响警告系统的电路设计与加改装工作。通过近一年的使用,我院1 72R基本型飞机再未出现空中断电的问题。
