The aim of the United Kingdom Radiotelephony Manual (CAP 413) is to provide pilots
and Air Traffic Services personnel with a compendium of clear, concise, standardised
phraseology and associated guidance, for radiotelephony communication in United
Kingdom airspace.
Radiotelephony (RTF) communications between United Kingdom air traffic services
units and pilots are expected to comply with the phraseology described in this
manual.
Operational details can be found in the United Kingdom Aeronautical Information
Publication (UK AIP). Phraseology for air traffic controllers (consistent with CAP 413)
is also published in the Manual of Air Traffic Services (CAP 493).
CAP 413 is also a useful reference for those studying for the UK Flight
Radiotelephony Operator's Licence.
Candidates for JAA pilot and instrument rating examinations should note that the
syllabus for the communications examination is drawn directly from the International
Civil Aviation Organisation (ICAO) Annex 10 Volume 2 and ICAO Doc 9432-AN/925
and not CAP 413.
