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
