company operating the aircraft should inform the

operating company and trip number, followed by the 
company name as displayed on the aircraft, and

7.  Phonetic Alphabet 

The 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 communica-

tions 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.
