(d) AWIB.

Aerodrome and Weather Information Broadcasts (AWIB)

A -Aerodrome
W -Weather
I -Information
B -Broadcasts

AWIB relays Information on meteorological and
operational conditions that are obtained from automatic sensors
and manual observations, which include:

(a) Preferred runway in use;
(b) Other operational information;
(c) Wind direction and strength;
(d) Visibility;
(e) Cloud cover;
(f) Temperature;
(g) QNH (if from a CAR Part 174 certificated source) or mean sea
level pressure.

An AWIB is an automated broadcast on a specified frequency at
some unattended aerodromes. It relays information on meteorological
and operational conditions that are obtained from automatic sensors
and manual observations.

An AWIB is not provided by an Air Traffic Service and is
therefore not required to have the same standard of accuracy as an
ATIS does.

The following information (which may be obtained
from automatic sensors, manual observations, or a combination of
both, and may vary with location) may be broadcast by an AWIB:

Pilots should note that MET information may not necessarily
be representative of the conditions in the vicinity of the runway
because of the siting of the AWS and the area of scan.

Frequencies and hours of operation for AWIB are provided in
GEN 3.7-1.

(c) AFRU;

Aerodrome Frequency Response Unit (AFRU)

An AFRU is a unit that provides confirmation to
pilots that they have selected the correct aerodrome
frequency, and that their aircraft radio is operating
correctly. It may operate as a supplementary device to
a ground facility (UNICOM) operating on the aerodrome
frequency, or it may be the
sole ground communications device.

If an aircraft operating within radio range of
the AFRU makes a transmission on the aerodrome frequency,
the AFRU will detect the transmission and automatically
respond on the frequency with either:

(a) A pre-recorded voice message, (normally the aerodrome
location and frequency) if no aircraft transmissions have
been received in the period (typically 5 minutes) preceding
the transmission; or
(b) A short tone burst if any transmissions have been
received in the preceding period.

(b) ATIS;

Automatic Terminal Information Service (ATIS)

ATIS is a continuous broadcast of the operational information

If a particular aerodrome has ATIS the Aerodrome Chart will indicate this with the appropriate frequency

Items normally included in the ATIS are:

– Name of Aerodrome Terminal Information
– Code letter of the Transmission
– Time Issued
– Expected type of Approach
– Runway in use
– Surface Conditions
– any other Operational Information
– Surface Wind in M and Knots
– Visibility
– Present Weather
– Cloud
– Temperature and Dew Point
– QNH
– 2000 ft wind
– Statement – ” on first contact with …tower / approach control notify receipt of Information (Bravo, Charlie etc)

(a) UNICOM;

Universal Communication (UNICOM) Services

UNICOM is not an air traffic service. UNICOM is an
air/ground communications facility providing an information
service at aerodromes with no aerodrome control or aerodrome
flight information service.

UNICOM is provided at:
(a) Ardmore aerodrome by Ardmore Airport Limited; and
(b) Mount Cook aerodrome by Aoraki Mount Cook Ski Planes Ltd.

UNICOM Information provided may include:
(a) Current aerodrome information and conditions;
(b) Basic weather information such as:
(i) Wind direction and strength;
(ii) Visibility;
(iii) Cloud cover;
(iv) Temperature; and
(v) QNH (if from a CAR Part 174 certificated source) or
mean sea level pressure.
(c) Meteorological reports (subject to certification under
Civil Aviation Rules Part 174);
(d) Aerodrome and Weather Information Broadcasts (AWIB).

The UNICOM operator may also provide other ancillary
services.

(l) Listening out;

Maintain a continuous listening watch on the appropriate frequency just prior to commencing to taxi for a flight and through the flight until the aircraft is brought to a stop in the parking position at flight completion.

Frequencies for listening watch are:

– Frequency for Air Traffic Control unit responsible for the controlled airspace
– Frequency for Air Traffic Control unit providing the aerodrome service at controlled aerodromes
– Frequency for the Flight Service Station providing the aerodrome flight information service
– Frequency for the ATS unit providing Flight Information Service for operations outside controlled airspace
– Frequency for the Unicom service associated with Mandatory Broadcast Zones
– 119.1 MHz or specified frequency for operations at and in vicinity of uncontrolled aerodromes

(k) Corrections and repetition tests;

If there is doubt that a message has been correctly received,
a repetition of the message should be requested in full or in part.

SAY AGAIN	Repeat entire message
SAY AGAIN (item)	Repeat specific item
SAY AGAIN ALL BEFORE (the first word satisfactorily received)	Repeat part of message
SAY AGAIN ALL AFTER
SAY AGAIN ALL BETWEEN AND

(j) Procedures for exchange of messages;

Items required for a clearance request are:
-Call sign (discrete transponder code if applicable)
-Position
-Level
-Intended route
-Destination
-Clearance request

The basic principles are:

Listen – Understand – Read Back – Comply

(i) Radiotelephony aircraft callsigns;

91.249 New Zealand registered aircraft must use one of the following radiotelephony call signs:

(1) The telephony designator of the aircraft operating agency as
approved by the Director(CAA), followed by the flight
identification; e.g: CHATHAM 84

(2) The telephony designator of the aircraft operating agency as
approved by the Director(CAA) followed by the last 3 letters of the
aircraft registration marking; e.g: CHATHAM DELTA ALPHA MIKE

(3) The name of the aircraft manufacturer, or the aircraft model,
and the last 3 letters of the aircraft registration marking.
e.g: CESSNA 152 MIKE DELTA SIERRA

Except for(2)above, the pilot-in-command may, after
establishing two-way communication with an appropriate ATS
unit, use an abbreviated call sign consisting of the last 3 letters of
the aircraft registration marking. e.g: MIKE DELTA SIERRA

Section 2.10 (i) Radiotelephony aircraft call signs;
4.6.2 Aircraft Callsigns
4.6.2.1 Information on aircraft callsigns for operations within New Zealand are contained in RulePart 91.
4.6.2.2 An aircraft callsign does not change during flight except for a temporary period on the instruction of ATC in the interests of safety.

ATC: FASTAIR 345 CHANGE YOUR CALLSIGN TO FASTAIR ALFA TANGO MIKE
A/C: FASTAIR ALFA TANGO MIKE WILCO
ATC: FASTAIR ALFA TANGO MIKE REVERT TO YOUR FLIGHT PLAN CALLSIGN AT (TIME/REP)
A/C: FASTAIR ALFA TANGO MIKE WILCO

The Director may only approve the call signs prescribed in
paragraphs
(1) and (2) above
(1) the holder of an air operator certificate issued under Part 119 or 129 conducting

(i) A regular air transport service; or
(ii) A search and rescue flight; or
(iii) A medical transfer or medical emergency flight; and

(2) Aircraft being flown on a police operation that is authorised by
the Commissioner of Police.

An applicant for the approval of a telephony designator must submit to the Director in writing the name of the aircraft operating agency and a payment of the appropriate application fee prescribed by regulations made under the Act.
