The traffic control arrangements of the Royal Aircraft Establishment, Farnborough, although they have never been the subject of intensive operational research, but have been derived by a process of steady growth, may be of interest as an example of what can be achieved by good organization on an ad hoc basis under some of the most difficult operational conditions.

The Royal Aircraft Establishment has an experimental airfield situated in a highly congested area. The London control zone and area is immediately to the north and east, and it is fringed on three sides by civil traffic lanes (Green Airway i in the north and north-west, Red i in the east, and the proposed Red 2 in the south). The Blackbushe circuit of the Ministry of Civil Aviation inter-locks with the Farnborough one in the north north-west, and the circuit of the Odiham R.A.F. airfield, from which jet aircraft are regularly operating, is situated only five miles away in the line of the main bad-weather runway.
