随着航空技术的不断发展,应用在B737飞机系列上A/P自动驾驶仪系统的电子设备已达到很先进的水平,机组人员可根据需要,毫不费力地拨动部分旋钮,在CPU荧光屏控制显示装置的键盘上打进去一些数据,使飞机在起飞、爬升,平飞、转弯、下降、着陆整个过程中实现自动指引、自动驾驶。因此,该系统在飞机上已成为非常重要的一个组成部分,它的工作正常与否,直接关系到飞行安全。A/P系统的机载设备很多,现将有关A/P系统部分的故障加以分析和总结,以供机务维护人员参考。
As aeronautical technology continues to evolve, the electronics used in the A / P autopilot system on the B737 family of aircraft have reached advanced levels and crew can effortlessly turn some of the knobs as needed, with the CPU-screen control Some data is displayed on the keyboard of the display device, so that the aircraft can automatically guide and take the initiative in taking off, climbing, leveling, turning, descending and landing throughout the process. Therefore, the system has become a very important part of the aircraft, its normal operation or not, is directly related to flight safety. The A / P system has many on-board equipment. The faults of the A / P system part are now analyzed and summarized for reference by maintenance personnel.
