Aeronautical phraseology is a set of communication rules for simplified English language communication between an air traffic controller and the pilot in command of an aircraft.
[1] In the majority of countries, the aeronautical phraseology in use is based on standards developed by the International Civil Aviation Organization.
[2] A primary goal of concise aeronautical phraseology is to enhance communication between pilot and control tower.
[3] Brevity is a further goal, since shorter communications segments mean the airwaves are available for other aircraft to contact the ATC.
[6][7][8] Radio contacts using aeronautical phraseology begin with an identifier call sign in the case of a pilot, or the name of the airport in the case of the control tower.
