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
