Heathrow just wanted to let you know that between 3 October and 18 December major construction work is required to rebuild one of the taxiways adjacent to the northern runway. The taxiway is used by aircraft exiting the runway after landing when the airport is on easterly operations. Its closure means that the number of aircraft that can land is restricted on that runway due to the longer time that planes will remain on the runway until they can exit using an alternative taxiway.
To maintain safe operations and mitigate the impact of this work, during periods of easterly operations we will have to land some aircraft (an extra two per hour) on the southern runway after 7am while the work is being carried out.
They have made every effort to minimise the impact on local communities – this timeframe was chosen due to lower traffic volumes and based on historic data there is a 20% risk of easterly operations during this period. However, they recognise that this may cause disruption to communities around the airport and therefore they wish to apologise in advance.
