Heathrow easterly alternation

The council, as Local Planning Authority, is currently considering a planning application (ref. 41573/APP/2024/2838) submitted by Heathrow Airport Limited, which proposes development works that would change the way Heathrow Airport operates.

Background

The northern and southern Heathrow runways both allow for take offs and departures. Departures are generally into a headwind and the prevailing wind from the south-west means approximately 70% of operations are in a westerly direction.

When planes are landing and taking off towards the west (known as westerly operations), Heathrow alternate the use of the two runways to provide local communities with respite. This means that for part of the day Heathrow use one runway for landings and the other for take-offs, then at 3pm, it switches over. At the end of each week, the pattern changes. 

At present, when planes take off towards the east (known as easterly operations), only the southern runway is used. This is the result of a historical arrangement known as the Cranford Agreement, which central government formally ended in 2009.

Proposal

The current planning application has been submitted by Heathrow Airport Limited to support the airport in alternating between the runways when on easterly operations. This would mirror the westerly operating patterns, although would result in new departures over communities that have not routinely experienced them. 

To enable the above changes, certain ground infrastructure works are required. These include the construction of a new, larger noise barrier in Longford and taxiway adjustments on the airfield to allow for the movement of aircraft between terminals and the northern runway.

It must be noted that the planning application does not allow for runway expansion or an increase in air traffic movements.
