摘　　要：在阐述航空近距导航系统的组成、三种工作状态及其工作原理的基础上,识别某型机载近距导航设备在连接近导信标模仿仪时指示器无指示的故障模式,分析故障原因,对故障点进行定位和排除,并结合实际经验,给出飞行器故障分析以及通电维护等方面的建议,对保证近距导航系统的正常使用和飞行安全具有一定借鉴意义。On the basis of expounding the composition, three working states and working principle of the airborne short-range navigation system, the no-indicating failure mode of a certain type of airborne short-range navigation equipment when connecting to the beacon simulator is identified, the causes of the failure are analyzed, the fault point is located and eliminated, and some suggestions about aircraft fault analysis, power-on check and maintenance are put forward based on practical experience. This paper has certain reference significance for ensuring the normal use of short-range navigation system and flight safety.
