The Airport normally use only Runway 1 at night but Runway 2 is used at night when maintenance work is being carried out on Runway 1. This is programmed in advance. For the rest of 2019, the programmed dates are as follows:
October 6th, 7th, 8th, 9th & 10th
November 5th, 6th & 7th
December 3rd, 4th & 5th
January (2020) 14th, 15th & 16th
It may be that unexpected maintenance work needs to be carried on dates other than those above.
Runway 2 is parallel to Runway 1 and about 500 yards South of it but is about a mile further away from Heald Green, so the aircraft will be higher than normal but 500 yards further South. The night period for this purpose is from 10pm until 6am, the following morning. Whether aircraft will be landing or taking off over Heald Green is determined by the wind at the time. Settled warm weather generally means easterly winds, which means that take-offs will be over Heald Green, just when you want to leave your windows open!
