This Advisory Circular (AC) describes an acceptable means of compliance with standard radiotelephony phraseology for use by pilots and air traffic services (ATS) and incorporates examples and guidance for managing ground vehicles. It is based on the following ICAO documents:
Civil Aviation Rules Part 172 Air Traffic Service Organisations – Certification, rule 172.105 Radio and telephone procedures lists the above order of precedence for these documents to be used in determining standard phraseology when communicating with pilots.
This AC relates to Civil Aviation Rule Parts 91 and 172 regarding communications requirements between pilots and ATS.
Revision 15 replaces Revision 14 which was published 1 June 2021. In Revision 15, the term “Essential Traffic” is reintroduced to sections 4.14.1 to 4.14.3 to reflect the wording in rule 172.3, Definitions, and in the New Zealand Aeronautical Information Publication (AIPNZ) ENR sections on Essential Traffic. We have also corrected some formatting errors, which has changed the page numbers of some sub-sections, by trying to keep tables on one page wherever feasible.
