§ Mr. Andrew F. Bennettasked the Secretary of State for Defence what is the area of United States Air Force controlled air space and its orientation, about the 626W following: Lakenheath, Mildenhall, Woodbridge and Bentwaters, Alconbury, Greenham common, Sculthorpe, Wethersfield, Kemble, Upper Heyford and Fairford.
§ Mr. LeeEach of the airfields is contained within an aerodrome traffic zone subject to the provisions of rule 35 of the Rules of the Air and Air Traffic Control Regulations. Aerodrome traffic zones extend laterally for 1.5 nautical miles from the airfield boundary and vertically to 2,000 ft above ground level. With the exceptions of Lakenheath and Mildenhall, which lie within the Honington military control zone, the airfields are also contained within military aerodrome traffic zones whose regulations are mandatory for military aircraft but advisory for civil airspace users. Military aerodrome traffic zones extend to a radius of five nautical miles from the centre of the airfield's main runway with additional stubs in line with the runway and extending to 10 nautical miles from its centre. The area of a military aerodrome traffic zone is about 118 sq miles. Those at Sculthorpe, Wethersfield and Greenham common are activated only when the airfield is in use.
Upper Heyford is additionally contained within a radar advisory service zone which covers an area of some 400 sq miles. The service provided is mandatory for military air traffic only. Civil aircraft in the vicinity of Upper Heyford may request a radar advisory service from military air traffic controllers if they so wish. New arrangements with regard to this aerodrome are planned to come into effect on 10 April.
