8. Transfer of Communications
An aircraft will normally be advised by the appropriate aeronautical station to
change from one frequency to another.
“SE-GPD contact Copenhagen Control 129,345”
“Copenhagen Control 129,345 SE-GPD”
8.1 Pilot’s Choice
If the pilot wishes to change frequency he should notify the change as
appropriate.
“Roskilde Approach, SE-GPD changing to Cophenhagen Control 133,3”
The ICAO Annex10 also has the following advice. “When establishing initial
contact, or when leaving, a VHF frequency, an aircraft station shall transmit such
information as may be prescribed by the appropriate authority”.
After a call has been made to an aeronautical station, a period of at least 10
seconds should elapse before a second call is made.
Stations having a requirement to transmit information to all stations likely to
intercept the call should preface the transmission with general call ‘ALL
STATIONS’, followed by the identification of the calling station. No reply is
expected unless individual stations are subsequently called to acknowledge
receipt.
8.2 Readback
8.2.1 Readback of Clearances
A clearance may vary from a detailed description of a route and levels to be flown
or it could be the name of a standard route such as a Standard Instrument
Departure (known as “SID”). Clearances should be passed slowly to enable pilots
to write down the information. If possible a clearance is passed before start up
and certainly not when a pilot is engaged in maneuvering his aircraft; of course,
multi-crew aircraft do not have a problem here.
