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. [4] [5]
The use of slang, jargon and chatting are strongly discouraged. [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. [3]
