目前,某型飞机在飞行过程中由于无应急航向测量仪表,当飞机主航向测量设备发生故障时,飞行员将失去航向参考,存在一定安全隐患。通过对飞机航向判读性能研究,得出有必要在该型飞机前、后舱加装应急磁罗盘,当飞机主航向测量设备发生故障时,飞行员可以根据应急磁罗盘指示判读飞机航向。
At present, when a certain type of aircraft has no emergency heading measurement instrument during flight, the pilot will lose heading reference when there is a failure of the main heading measurement equipment of the aircraft, which poses a potential safety hazard. Through the study of aircraft heading readability, it is concluded that it is necessary to install an emergency magnetic compass in front of and behind the aircraft. When the main heading measurement device fails, the pilot can interpret the aircraft heading according to the emergency magnetic compass instruction.
