4-2-7 Phonetic Alphabet
AIM Chapter 4. Air Traffic Control — Section 4-2, Radio Communications Phraseology
Official text — AIM 4-2-7
AIM — FAA OPERATIONAL GUIDANCEThe International Civil Aviation Organization (ICAO) phonetic alphabet is used by FAA personnel when communications conditions are such that the information cannot be readily received without their use. ATC facilities may also request pilots to use phonetic letter equivalents when aircraft with similar sounding identifications are receiving communications on the same frequency. Pilots should use the phonetic alphabet when identifying their aircraft during initial contact with air traffic control facilities. Additionally, use the phonetic equivalents for single letters and to spell out groups of letters or difficult words during adverse communications conditions. (See TBL 4-2-2.)
