PILOT/CONTROLLER

GLOSSARY

PURPOSE

a.

This Glossary was compiled to promote a common understanding of the terms used in the Air Traffic

Control system. It includes those terms which are intended for pilot/controller communications. Those terms

most frequently used in pilot/controller communications are printed in bold italics. The definitions are primarily

defined in an operational sense applicable to both users and operators of the National Airspace System. Use of

the Glossary will preclude any misunderstandings concerning the system’s design, function, and purpose.

b.

Because of the international nature of flying, terms used in the Lexicon, published by the International

Civil Aviation Organization (ICAO), are included when they differ from FAA definitions. These terms are

followed by “[ICAO].” For the reader’s convenience, there are also cross references to related terms in other parts

of the Glossary and to other documents, such as the Code of Federal Regulations (CFR) and the Aeronautical

Information Manual (AIM).

c.

This Glossary will be revised, as necessary, to maintain a common understanding of the system.
