Communication
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.
Let's look at an example. Copenhagen Information cannot call OY-CTZ, but tries
to have a message sent through OY-DYT.
It could happen like this:
OY-DYT Copenhagen Information
Copenhagen Information OY-DYT
O-YT Copenhagen Information requests you to send MESSAGE TO OY-
CTZ
WILCO O-TY
O-TY TO OY-CTZ change frequency to Copenhagen information West
129.475
OY-CTZ here OY-DYT MESSAGE FROM Copenhagen Information
change to Copenhagen Information West frequency 129.475
OY-DYT from OY-CTZ MESSAGE TO Copenhagen Information OY-
CTZ changes to West on 129.475
Yes, then we got that message – a bit embarrassed that we forgot to switch to
the West frequency, but good thing Captain Cook in OY-DYT could act as a relay
station
