1.10.5 When a station is called but is uncertain of the identification of the calling station, the
calling station should be requested to repeat its callsign until identification is
established.
1.11 Corrections and Repetitions
1.11.1 When an error is made in a transmission the word 'CORRECTION' shall be spoken,
the last correct group or phrase repeated and then the correct version transmitted.
1.11.2 If a correction can best be made by repeating the entire message, the operator shall
use the phrase 'CORRECTION I SAY AGAIN' before transmitting the message a
second time.
1.12 Acknowledgement of Receipt
Acknowledgements of information should be signified by the use of the receiving
stations’ callsign or Roger callsign, and not by messages such as: 'callsign-copy the
weather' or 'callsign-copy the traffic'.
1.13 Transfer of Communications
1.13.1 To transfer communications with an aircraft to another unit, controllers shall pass
instructions giving:
a) the identity of the unit to be contacted;
b) the frequency to be used for contact.
Transfer of communication instructions should be passed in a single message. Items
which require a read-back should normally be passed in a separate transmission
before transfer.
1.13.2 If no further communication is received from the pilot after an acknowledgement,
satisfactory transfer of communication may be assumed.
1.13.3 An aircraft will normally be advised by the appropriate aeronautical station to change
from one radio frequency to another in accordance with agreed procedures.
In the absence of such advice, the aircraft shall notify the aeronautical station
before such a change takes place.
Aircraft flying in controlled airspace must obtain
permission from the controlling authority before changing frequency.
1.13.4 An aircraft may be instructed to ‘standby’ on a frequency when it is intended that the
ATSU will initiate communications, and to monitor a frequency on which information
is being broadcast.
