Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment he has made of Heathrow airport's ability to meet the Civil Aviation Authority's design principles on airspace changes as a result of precise flight paths associated with the expansion of the airport not yet being known.

As part of its airspace change process, the Civil Aviation Authority (CAA) is responsible for assessing the individual airspace design principles put forward by an airspace change sponsor.

In the case of Heathrow, the CAA was satisfied that the airspace design principles put forward by the airport met its regulatory requirements.
