某型飞机无线电高度视频判读方法及其在排故中的应用研究

Research on Radio Altitude Video Interpretation Method of a Certain Aircraft and Its Application in Troubleshooting

针对某型飞机无线电高度表维护过程中遇到的地面工作正常、空中工作不正常的疑难故障,提出了利用平显记录视频进行无线电高度视频判读的故障分析方法。介绍了无线电高度在平显上的基本显示,总结分析了不同飞行状态下无线电高度的显示逻辑,并针对视频判读典型故障案例进行了研究分析,研究结果可用于无线电高度表的故障分析和定位。

This paper proposes a fault analysis method using the HUD record video to interpret radio altitude.This method works for the trouble of normal ground work but abnormal air work during the maintenance of radio altimeter on a certain aircraft.The basic display of the radio altitute on the HUD is introduced,and the display logic of the radio altimeter in different flight states is summa-rized.A case study is conducted on a typical fault in video interpretation,the research results of which can be used for fault analysis and positioning of radio altimeter.
