The Department for Transport does not hold such information on private helicopter movements. However in response to the London Assembly Environment Committee's report—‘London in a Spin; a Review of Helicopter Noise’ in October 2006, the Department agreed with the Civil Aviation Authority that NATS would provide data on helicopter movements over London. This information is now published at regular intervals on the CAA website at the following link:
The tables published by CAA show data for helicopter movements within the London (Heathrow) and London City control zones (CTRs) from January 2007 to date.
As regards information prior to January 2007, the London Assembly report included a year-by-year total for the period 1997 to 2006 for commercial and non-commercial helicopter movements at Metro London Heliport at Battersea.
