To ask the Secretary of State for Transport what proportion of air travel from Stansted airport was accounted for by(a) residents of the south east of England, (b) residents of other parts of the UK and (c) overseas residents, in the last year for which figures are available; and if he will make a statement.

§ Mr. Jamieson
No noise preferential routes have been determined for any of the possible additional runways in the consultation document. Aircraft arrival and departure routes were developed for various airport locations to assist with the modelling of noise exposure and local air quality, so that the relative impacts of the many runway development options could be compared.
Routes to and from new runways in all the airport options were derived in essentially the same manner. Routes to and from existing runways were left unchanged wherever practical, and routes for new runways were based on the existing airspace structure of airways, waypoints, holding areas etc.703W
Arrival routes to all runways were assumed to be straight in on the runway heading. Departure tracks for new runways at an airport, and existing runways where necessary, were based on existing departure routes as far as practical.
In practice, the development of one or more new runways in the south east would require substantial changes to the region's airspace structure which could affect thefinal configuration of routes. It was not feasible to predict in detail how airspace in the south east might need to be reorganised in the long term to cater for increased activity. As part of the SERAS study, CAA and NATS did carry out a high level assessment of the overall pressures on airspace of sample combinations of new airport capacity up to 2030 and concluded that the increase in air traffic could be accommodated.
