Public Safety Zones - Heathrow : End of Cranford Agreement

T Henderson made this Freedom of Information request to Civil Aviation Authority

This request has been closed to new correspondence from the public body. Contact us if you think it ought be re-opened.

The request was successful.

Dear Civil Aviation Authority,

I note that Hillingdon Council is currently seeking comments on a planning application by Heathrow Airport to undertake works associated with the ending of the Cranford Agreement whereby currently planes do not usually take off from the northern runway in an easterly direction.

The associated Health and Equalities Impact Assessment mentions the possibility of changed Public Safety Zones connected with the change in flight movements :

Issue: whether the public safety zones at the end of the northern runway are going to be changed
as a result of the proposed changes. Under the Cranford Agreement flights would depart in an
easterly direction from the northern runway only in exceptional circumstances. If the Cranford
Agreement is lifted then easterly flights from the northern runway would become more frequent.

Does this mean that the safety zones would change?
 Response: HAL to discuss with Department for Transport. The established Public Safety
Zones will need to be remodelled by NATS, the National Air Traffic Service. Exactly how and
when this will occur is the subject of discussions with the Civil Aviation Authority.

Under the Freedom of Information Act please can you provide me with information held by the CAA regarding the changes in Public Safety Zones associated with the ending of the Cranford Agreement and the process of establishing it.

It would appear that the mechanism outlined by the previous Minister regarding Public Safety Zones and planning applications in connection with the potential third runway at Heathrow is not being followed :

Yours faithfully,

Tim Henderson
