The ADF provides the pilot with an indication of the direction of radio signals received from selected stations operating in the low and medium frequency range of 90 kHz to 1800 kHz. The Automatic Direction Finder ADF is an aircraft navigation product that automatically calculates the relative bearing of the aircraft to the radio station. 05112020 wtruib training NAVIGATION No Comments. The Automatic Direction Finder ADF - when tuned to a selected NDB frequency is the on-board equipment that determines the relative bearing RB from the aircraft to the ground beacon or station.

AUTOMATIC DIRECTION FINDER ADF SYSTEM.

121 Receiver The RCR-650D Receiver processes the ANT-650A Antenna signal to derive the relative bearing between the centerline of the aircraft and the selected station. The ADF receiver a backup system for the VHF equipment can be used when line-of-sight transmission becomes unreliable or when there is. One of the older types of radio navigation is the automatic direction finder ADF or non-directional beacon NDB. Automatic direction finder system Download PDF Info Publication number US3099009A. The Doppler Radio Direction Finder. It provides aircraft bearing information with respect to a ground station known as NDB Non Directional Beacon.
