London Area Control Centre

The London Area Control Centre is an air traffic control centre based at Swanwick near Fareham in Hampshire, southern England. It is operated by National Air Traffic Services, starting operations on 27 January 2002, and handles aircraft over England and Wales. Internally within NATS it is usually known by the initials AC.
LACC shares the Swanwick site with the London Terminal Control Centre, which moved there in 2007.
AC-based controllers provide air traffic services mainly within the London Flight Information Region. This airspace is split into five Local Area Groups which relate to the position of the airspace sector groups within the FIR. All sectors have the R/T callsign \"London Control\".
Also within the AC Operations room sit the FIR Flight Information Service Officers who provide an information service to aircraft operating within the London FIR as a whole using the callsign \"London Information\". 'London Military' controllers are also based in the AC Operations room.
