§ Mrs. May
To ask the Secretary of State for Transport (1) what advice he received from the National Air Traffic Service on the feasibility of the proposals 1117W contained in the White Paper on "The Future of Air Transport" (a) prior to publication of the White Paper and (b) subsequently; 
(2) what assessment his Department has made of the impact of the proposals in the White Paper on "The Future of Air Transport" on the design of UK airspace; 
(3) what discussions his Department has held with the National Air Traffic Service on the impact of increased airport capacity at (a) Heathrow and (b) Stansted on the design of London Terminal Area airspace; 
(4) what simulations have been undertaken by the National Air Traffic Service of the impact of increased airport capacity in the South East on the design of London Terminal Area airspace; 
(5) what assessment he has made of how long it will take the National Air Traffic Service (NATS) to (a) design and (b) implement changes necessary to the London Terminal Area airspace as a result of the proposed increases in airport capacity in the South East; and when NATS expects to begin this work. 
§ Mr. Darling
The studies that preceded "The Future of Air Transport" included a high-level assessment of airspace issues by the Civil Aviation Authority (CAA), the body responsible for the planning and regulation of UK airspace, and National Air Traffic Services (NATS). This work concluded that the necessary airspace capacity could, in broad terms, be provided safely through the redesign of airspace and the introduction of enhanced air traffic techniques and systems. Copies of the relevant report have been placed in the House Libraries. Both organisations also responded to the consultation that preceded the White Paper. In their response, NATS supported the need for new runways in the South East and expressed a preference for development at existing airports.
Paragraphs 12.25-12.27 of "The Future of Air Transport" set out the Government's expectation that the CAA will make early progress in bringing forward a programme of work, involving other key bodies including NATS, for the redesign of airspace to accommodate forecast growth in air traffic.
