The civilian part of the West Drayton site closed in November 2007, when its functions moved to Swanwick, Hampshire.
In the early 1990s the 'Central Control Facility' (CCF) was formed within the centre to provide terminal control services to aircraft arriving at and departing from the main London airports, subsuming the existing terminal sectors in preparation for the arrival of the London area airport approach units.
[1] In 1992 the Heathrow and Gatwick approach control units moved to West Drayton to share facilities with the CCF.
In 1995 Stansted approach control, soon after to be renamed Essex Radar, moved to West Drayton to take their place in the TCR.
The West Drayton facility was renamed the London Terminal Control Centre (LTCC - though still pronounced "latsea") at this time.
