This policy information paper provides information about the Radiocommunications (Aircraft and Aeronautical Mobile Stations) Class
Licence 2006 (the Aircraft and Aeronautical Mobile Stations Class
Aircraft and Aeronautical
Mobile Stations Class Licence
and Aeronautical Mobile Stations Class Licence came into force on 6
September 2006. It authorises the operation of a range of aeronautical
radiocommunications and radionavigation equipment fixed to, or carried
on-board, all aircraft including recreational aircraft. Recreational aircraft
include ultralights, trikes, hang gliders, paragliders, gyrocopters, gliders,
sailplanes, other like craft and balloons. It also authorises most ground-based
aeronautical mobile radiocommunications equipment operating on the common group
of aviation frequencies.
Operators of aircraft and aeronautical mobile stations are subject to
conditions specified in the Class Licence, and the Radiocommunications Act 1992 (the Act).
Operators are also required to comply with the relevant mandatory standards,
equipment specifications or equipment compliance requirements specified in the
Aeronautical Mobile Stations Class Licence.
Equipment required to be fitted to, or carried on, an aircraft under Civil
Aviation Regulations must also comply with the relevant Technical Standard
issued under the Civil Aviation
and Aeronautical Mobile Stations Class Licence authorises any qualified
operator to operate an aircraft station that uses a frequency:
- on or within a range of frequencies, mentioned in the Schedules of the
class licence or
- published in the Aeronautical Information Publications (AIP) made under
Regulation 4.12 of the Air Services
The use of INMARSAT satellite frequencies is authorised under the Radiocommunications
(Communication with Space Object) Class Licence 1998.
The use of Emergency Position Indicating Radio Beacons (EPIRBs) is
authorised in the Radiocommunications
(Emergency Locating Devices) Class Licence 2006.
Transmitter power levels
Equipment authorised under the Aircraft and
Aeronautical Mobile Stations Class Licence must not exceed the maximum
power specified in the relevant standard, equipment specification or equipment
Section 132(3) of the Act provides that:
'Operation of a radiocommunications device is not authorised by a Class
Licence if it is not in accordance with the conditions of the licence.'
For instance, an aircraft or aeronautical mobile station operator is in
breach of a class licence condition if the operator is operating on frequencies
not authorised by the applicable class licence.
Only qualified persons under the Civil Aviation Regulations and the relevant
Civil Aviation Orders may operate aircraft and aeronautical mobile
Under the Aircraft and Aeronautical Mobile Stations Class Licence,
operators must ensure that the aircraft station or the aeronautical mobile
station must identify the station using a suitable form of identification.
The operator of an Aircraft station uses call signs as a form of
identification that clearly identifies the station. Call signs are a unique
series of letters and/or numbers allocated to identify a station. Call signs
must be used for all on-air communications including testing. Call signs
allocated to Aircraft stations conform with International Telecommunication
Union Radio Regulations.
CASA requires that radiocommunications call signs used by
Australian-registered aircraft either reflect the official aircraft
registration markings (VH-aaa) or a word designating the airline followed by
the flight identification number.

Aircraft stations should employ, as a call sign, their registration marking
or an abbreviation of such letters and company titles, in accordance with
procedures outlined in the aeronautical information papers issued by Airservices Australia.
For air safety reasons, CASA requires
that callsigns for recreational aircraft, use a call sign format that cannot,
in any circumstances, be confused with Australian-registered aircraft.
Ultralight aircraft are registered with the Australian Ultralight Federation (AUF) and
their registration marking are used as call signs. The aircraft type should be
used ahead of the call sign. (Eg "DRIFTER, 2, 1, 2, 1".)
Trikes (powered hang gliders) are registered with the Hang Gliding Federation of Australia (HGFA)
and their registration markings are used as call signs.
Hang gliders and paragliders use call signs derived from pilot's certificate
registrations issued by the HGFA.
Gyrocopters are registered with the Australian Sport Rotorcraft Association
Incorporated (ASRA) and the registration is used as the call sign.
Glider and Balloons are registered as aircraft by CASA and the registration
is used as the call sign.
The call sign formats for the various types of recreational aircraft is
Recreational Aircraft Type
Call sign Format
(aircraft type) nnnn
Trikes (powered Hang Gliders)
TRnnn or TCnnn
Gnnn and Gnnnn
Note: n = numeric character 0 - 9 a = alpha character a - z
The registration provided for recreational aircraft by the relevant sport's
controlling body is only valid in Australia. The use of 'Ua', 'TR', 'TC', 'HG'
and 'G' prefix call signs for these stations are therefore limited to use
Aeronautical mobile stations
The operator of an aeronautical mobile station must use a form of
identification that clearly identifies the station.
Aircraft that travel beyond Australian territories will need to carry a
certified signed copy of the Aircraft and
Aeronautical Mobile Stations Class Licence (refer to section 139, Volume 3
of the Civil
Aviation Regulations 1988). This may be arranged by making a request in
writing, including information about the aircraft's registration markings,
