Departing aircraft normally do not use the northern runway on easterly operations due to the Cranford Agreement. This is an oral agreement between the Government and the residents of Cranford which has existed since the mid-1950s.
This agreement was designed to protect the residents of Cranford, which is very close to the eastern end of the northern runway, from the high noise levels experienced on the ground from departing aircraft which are at low altitudes over Cranford. However, overflight is permitted when necessary, for example when the southern runway is closed, e.g for maintenance works
g) The Cranford Agreement (as it applies today)
29.This is a 1950s undertaking to avoid easterly take-offs from the northern runway (09L) over Cranford when ever possible. Until the main runways were extended westward in the 1960s Cranford was the nearest residential area to the airport situated under the approach and departure tracks. It is not a written agreement, but is understood to have been a "best endeavour" undertaking given at a public meeting in 1952. The main effect of the restriction is to require take-offs to use the southern runway (09R) during easterly operations, which in turn means that most easterly landings must overfly Windsor and Poyle to use the northern runway (09L), thereby precluding runway alternation during easterly operations in the daytime.

Any problem with 27R for landing? Aircraft fly over the same neighborhood when landing on 27R as they do when taking off from 9L. My guess is that landings are a little quieter than takeoffs, so they don't create as much as a problem???
