GEN 2.2 ABBREVIATIONS AND DEFINITIONS USED INAIS PUBLICATIONS

1 ABBREVIATIONS

1.1 General

1.1.1 The abbreviations used in the AIP New Zealand are generally inaccordance with those listed in ICAO Abbreviations and Codes PANS-ABC(Doc 8400), and CAR Part 1.

1.1.2 Abbreviations are correct in the use of upper and/or lower casewhere there is an applicable international standard, such as for units ofmeasurement (ICAO ANNEX 5). Upper case is always used incommunications on the aeronautical fixed service, such as transmission onthe international AFTN, or in the text of NOTAM.

1.1.3 A shortened list of abbreviations is also available on the Airwayswebsite.

1.1.4 In the following listing:

* means a non-ICAO abbreviation — for New Zealand domesticuse only

† means abbreviations and terms are to be transmitted as spokenwords when using radiotelephony

‡ means abbreviations and terms are to be transmitted asindividual letters when using radiotelephony

The computer-resolved verticalguidance is based on barometric altitude and is specified as a vertical pathangle from RDH.

Baro-VNAV approach procedures utilise a DA/H and not an MDA/H, andneither a FAF nor a missed approach point (MAPt) is identified, instead theyutilise a final approach point (FAP) only. They use obstacle assessmentsurfaces similar to those for ILS, but based on the specific RNAV lateralguidance system.

Note: Change-over points are established to provide the optimum balancein respect of signal strength and quality between facilities at all levels to beused and to ensure a common source of azimuth guidance for all aircraftoperating along the same portion of a route segment.

Controlled aerodrome: An aerodrome at which air traffic control serviceis provided to aerodrome traffic.

Note: The term controlled aerodrome indicates that air traffic controlservice is provided to aerodrome traffic but does not necessarily imply thata control zone exists.

For VFR flights, the time at which it is estimated that the aircraft will arriveover the aerodrome.

Estimated time of departure (ETD): The estimated time at which theaircraft will commence take-off.

Estimated time over (ETO): The estimated time over a significant point.
