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.
Revision 16 adds section 188.8.131.52 to clarify that a remotely piloted aircraft will contain the prefix ‘Remote’ in the aircraft callsign and adds REMOTE to the table under section 4.5, Standard words and phrases. This has been added for clarification as CAA are now issuing callsigns, where required, as part of issuing a Part 102 operating certificate.
