4.11.2.3 Ground station procedures in case of radio failure

If a ground station cannot contact you, it will try other options, e.g. transmitting

navigation aids that the ground station knows you are using.

The ground station will also blindly transmit to you and e.g. give instructions

that if you hear the message, then SQUAWK Ident or similar.

The ground station can also ask you to make a turn in a certain direction, and
if it sees you doing this, it can give further instructions.

Ex: "OY-BKA Billund TWR if you read me make a left turn - I say again OY-

BKA if you read me make a left turn"

The rules stipulate that an aircraft that has a radio failure and is flying VMC
must attempt to establish contact with the aerodrome by all means

(telephone – data link), and if this is unsuccessful, it must continue VMC and

land at the nearest suitable aerodrome, regardless of whether radio contact

is required.

He must then report landing.

During the approach, he must watch for light signals from the tower.

4.11.3 Forwarding messages

When flying in areas with poor radio coverage or when flying at low altitude, it

is not always possible to reach the unit you are calling.

A radio station may also have problems calling an aircraft.

In such cases, an aircraft at high altitude can be helpful in forwarding messages.
