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.
