provided.
3.2.6 Aircraft making the normal inbound or taxiing broadcast receive a
responding broadcast from the CA/GRS operator, conveying the
following information:
a. Confirmation of correct MBZ frequency or CTAF selection.
b. Current, known, relevant traffic in the MBZ or CTAF area and
on the manoeuvring area of the aerodrome. Traffic information
may include some or all of the following:
(1) the call-sign, aircraft type, position and intention; or
(2) where circuit flying is in operation, general advice on the
number of aircraft in the circuit, and position in the circuit
if relevant.
Note: This information is provided to assist pilots in arranging
self-separation.
c. Weather conditions and operational information for the
aerodrome. The information which may be advised includes:
GEN TOC ENR TOC AD TOC Index
GEN (GENERAL) A/L 45 effective 24 NOV 05
(1) runway favoured by wind or for noise abatement,
(2) wind direction and speed,
(3) runway surface conditions,
(4) aerodrome QNH,
(5) aerodrome surface temperature, and
(6) estimated cloud base and visibility and present weather.
This information will be provided by means of an Automatic
Aerodrome Information Service (AAIS) broadcast on a
discrete published frequency (similar to ATIS). Pilots should
monitor the published AAIS frequency before making the
taxiing or inbound broadcast, and indicate that the AAIS
information has been received when making the inbound or
taxiing broadcast.
d. Other operational information of a local nature, relevant to the
safety of operations at the aerodrome.
3.2.7 The CA/GRS will provide emergency services call-out if requested
by the pilot in an emergency or, if in the opinion of the operator, a
call-out is warranted.
3.2.8 The CA/GRS satisfies the requirement for straight-in approaches
by commercial passenger aircraft at non-controlled aerodromes
where the provisions of CAOs 82.3 and 82.5 apply.
3.2.9 The weather information provided by the service is derived from
approved measuring equipment, which meets BoM aeronautical
precision standards. QNH provided by a CA/GRS or AAIS may be
used to reduce landing, circling and alternate minima in
accordance with ENR 1.5 para 5.3.1 (QNH Sources).
3.2.10 The CA/GRS operator may act as a representative of an air
operator (where formal agreement with the operator has been
established) for the purposes of holding SARWATCH.
3.3 UNICOM
3.3.1 Unicom (Universal Communications) is a non-ATS
communications service provided on the MBZ frequency or CTAF
to enhance the value of information normally available about a
non-controlled aerodrome.
3.3.2 The primary function of the frequencies used for Unicom services
(MBZ/CTAF) is to provide the means for pilots to exchange traffic
information for separation purposes. Unicom services, being a
GEN TOC ENR TOC AD TOC Index
GEN (GENERAL) A/L 45 effective 24 NOV 05
secondary use of these frequencies, must not inhibit the exchange
of traffic information.
3.3.3 Participation in Unicom services relates to the exchange of
messages concerning:
a. fuel requirements;
b. estimated times of arrival and departure;
c. aerodrome information;
d. maintenance and servicing of aircraft including the ordering of
parts and materials urgently required;
e. passenger requirements;
f. unscheduled landings to be made by aircraft; and
g. general weather reports.
3.3.4 This information is available to all aircraft during the times that the
Unicom is operating.
3.3.5 Weather reports, other than simple factual statements about the
weather, may not be provided by Unicom operators unless they
are properly authorised to make weather observations under CAR
120.
3.3.6 The Unicom operator is solely responsible for the accuracy of any
information passed to an aircraft, while the use of information
obtained from a Unicom is at the discretion of the pilot in
command.
3.3.7 Stations providing a Unicom service are required to be licensed by
the Australian Communications Authority (ACA). Detailed
information regarding the licensing and use of equipment may be
obtained by contacting the ACA in the appropriate State or
Territory capital city.
3.3.8 Unicom operators must comply with the requirements of CAR 83
(2).
3.4 Aerodrome Frequency Response Unit
3.4.1 To assist pilots’ awareness of inadvertent selection of an incorrect
VHF frequency when operating into non-controlled aerodromes, a
device known as an Aerodrome Frequency Response Unit
(AFRU) may be installed. An AFRU will provide an automatic
