From Wikipedia, the free encyclopedia

A Control Area (CTA) is an aviation term that describes a volume of controlled airspace that exists in the vicinity of an airport. It has a specified lower level and a specified upper level. It usually is situated on top of a Control Zone and provides protection to aircraft climbing out from the airport by joining the low-level control zone to the nearest airways. In the UK they are generally Class A, D or E.

Control areas are particularly useful where there are busy airports located close together. In this case a single CTA will sit over all of the individual airports' CTRs. In larger-scale cases, this is known as a Terminal Manoeuvring Area (TMA).
