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.

Terms used in this glossary that apply to flight service station (FSS) roles are included when they differ

from air traffic control functions. These terms are followed by “[FSS].”

d.

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