机载ADF设备包括:ADF接收机,控制盒,方位指示器.环形天线和垂直天线几大部分,其工作原理是通过接收机接收和处理环形天线和垂直天线收到的地面导航台的信号,并将处理后的方位信息送到方位指示器(数字式方位信息送至EFIS),显示出飞机与地面导航台的相对方位,分离出来的地面导航台的音频识别信号送至机上音频系统(见附图)。只有熟知ADF工作原理,才能在实际排故工作
Airborne ADF devices include: ADF receivers, control boxes, azimuth indicators. Most of the loop and vertical antennas work by receiving and processing signals from ground-based navigation stations received by loop and vertical antennas at the receiver, And sends the processed bearing information to the azimuth indicator (the digital bearing information is sent to EFIS) showing the relative bearing between the aircraft and the ground navigation station. The separated ground navigation station’s audio identification signal is sent to the onboard audio system (see Drawing). Only familiar with the working principle of ADF, in the actual troubleshooting work
