QUJ True bearing to a facility

VHF DF (VDF)
Most air traffic control units (usually on Approach Frequency) are able to give

pilots bearing or direction information based upon the pilot’s transmission. The

direction finding equipment can give a “steer”(QDM) towards the aerodrome or
the pilot’s true (or magnetic) bearing from the airfield (QTE or QDR).

The pilot in this case could also request a steer e.g.

“QDM QDM QDM Roskilde Approach SE-GPD request QDM SE-GPD”
the transmission ends with the aircraft call sign repeated.

NOTE: The heading takes no account of wind effects (drift).

Class of Bearing

The class of bearing refers to the accuracy of the bearing information as follows:
Class A within ± 2°

Class B within ± 5°

Class C within ± 10°
Class D less accurate than Class C

3.7 RADIOTEST PROCEDURES

Before flight, it is wise to ensure that your radios will transmit and receive

properly. In order to do this a standard procedure is followed for each radio
requiring a test.

The meaning of this scale is as follows:
