For now, the runway change only takes place in the west (when planes disembark from London and take off towards Windsor). This is due to the legacy of the Cranford Agreement, founded in the 1950s. Cranford is a village at the eastern end of the north runway. The agreement prevented planes from taking off over the village, except in exceptional circumstances, and applied when Heathrow was in eastern service. The Royal Borough of Windsor and Maidenhead is calling on Heathrow not to delay measures to reduce noise pollution in Windsor, Datchet, Wraysbury and Horton. The district wants Heathrow to advance the end of the Cranford Agreement, created in the 1950s. It prevents planes from taking off over the village of Cranford, at the eastern end of the north runway, when Heathrow is in operation east. This means that Cranford is protected from the worst starting noise. But that means areas near Windsor receive all landings on the north runway instead of dividing them between the runways. Windsor suffered more noise because of the Cranford agreement. They always wanted it to end. At a recent meeting of Heathrow Airport`s advisory board, Heathrow Airport Ltd said it would wait until the third runway gets final approval before launching alternative runway plans in the eastern operation – meaning the Cranford deal remains. And Windsor continues to receive the noise.
Cllr Bowden von Windsor said: „The Council is extremely concerned about Heathrow Airport`s decision to further delay the runway change without public consultation.“ It would be even worse for the borough, with a 3rd track. . Tweet On February 2, later after the NPS announcements and airspace consultation, the DfT added the news that the government had agreed to terminate the Cranford agreement. This would have been an important announcement in itself, but cleverly buried along with the other news. The Cranford Agreement was an undertaking launched some sixty years ago, according to which planes heading east would only use the southern runway, not the north runway. This protects the people of Cranford from appalling noise. The end of the deal means less noise from arrivals (if the airport is located on easterly winds – about 30% of the year) from the west – so places like Windsor, Datchet, Colnbrook and Poyle – below the northern approach runway – could have half as many arrivals per day (about 330 instead of 630).
