Millions of Londoners live under Heathrow's flightpath and are impacted by the airport's close proximity to the capital, but it is not everyday that planes destined for Heathrow fly over the city.
Planes Over London provides a 14-day forecast as to whether Heathrow arrivals will be flying their approach over London. It gives visitors a 14 day forecast and a live view of what's happening now. It shows the runway currently in use and it carefully tracks the number of daily landing including delayed arrivals.
Incoming aircraft overfly the city about 70% of the time. When a strong tailwind blows they instead approach from the west over Windsor Castle, avoiding London altogether.
