I agree that this is unwelcome, but, to be fair, your topic heading is somewhat misleading. What has been announced, as you say in the text, is that the northern runway will be used for all night-time landings from Monday evening to Saturday morning. In practice that means that the average of 16 early morning landings between 04:00 and 06:00 will be on the northern runway on Tuesday, Wednesday, Thursday, Friday and Saturday mornings, and on the southern runway on Sunday and Monday mornings. This is instead of the normal pattern for night flights of alternating fortnights on each runway.If the wind directions during the summer are typical, it would mean night flights over Brentford for 53 nights during the 20-week period instead of the usual 37 nights.
