ADF Orientation
The pointer end of the ADF navigation unit ALWAYS POINTS TO THE STATION. The degree reading on the display is dependent on the aircraft heading.
U/V ADF: UHF/VHF Automatic Direction Finding.
UHF/VHF Automatic Direction Finding (U/V ADF): An Automatic Direction Finder that determines relative bearing to a transmitter to which it is tuned, in either the UHF band or VHF band.
The ADF indicator does not have a flag to indicate to the pilot if reception is reliable. You will need to listen to the station.

ADF Automatic Direction Finder, a radio navigation instrument. ADF uses AM radio signals. A needle on the instrument points in the direction from which the signal originates.
Automatic Direction Finder (ADF): A radio device that uses radio transmissions from ground stations to automatically indicate the bearing of an aircraft in relation to the ground transmitter.
Direction is indicated to the pilot as a magnetic bearing or as a relative bearing to the longitudinal axis of the aircraft depending on the type of indicator installed in the aircraft. In certain applications, such as military, ADF operations may ...
