Phraseology

Phraseology is the standardized set of words and expressions used in aviation radio communication. It is used between pilots and ATS units so messages are short, clear, and understood in the same way by everyone. You use it during normal radiotelephony, especially for requests, clearances, reports, and readbacks. As a pilot, you should know the standard forms, listen carefully, and use plain language only when standard phraseology is not enough to keep communication safe.
