When initiating a transmission toAir Traffic Services (ATS), you should
commence the transmissionwith the callsign of the unit being addressed
followed by the aircraft callsign e.g. ‘BrisbaneCentre, AlphaBravoCharlie
.........’.
When you read back anATSmessage you should add the aircraft callsign at
the endof the transmission.
Broadcasts by aircraft in the vicinity of non-towered aerodromes should be
prefixedwith the location followed by theword “traffic” and the aerodrome
name should also be added to the end of the transmission e.g. ‘Bathurst
traffic .......... Bathurst’. This is toemphasise the location in situationswhere
more than one aerodromemay use theCTAF frequency.
