To ask the Secretary of State for Transport how many aircraft routes cross High Wycombe and Marlow at 7,000 feet or less; what the height of each route is; how many planes per hour on average flew along each of those routes during (a) night time, (b) daytime and (c) at peak times in the last 12 months; how many planes per hour on average are expected to fly along each of those routes during (i) night time, (ii) daytime and (iii) at peak times in 2014; and whether she has made an estimate of the likely impact of air traffic noise on levels in High Wycombe and Marlow in 2014.

On the airspace change process, I refer the hon. Member to my earlier answer to his question today (UIN 191596).
