From Heathrow
Planes land and take off into the wind, so the weather decides which way Heathrow flies, and that decides how many pass over TW6. Across its postcodes, January to August 2026:
- On a day it flies west (56% of days): up to 225 a day; of its 123 postcodes, 15 on an edge, 108 under 10

On an edge: the postcode is on the edge of a flight path, where a few metres decide whether a plane counts as overhead, and the fewest and the most within 100 m of it fall in different bands.
1 of its postcodes have a position ONS estimates, so their figures may be for a spot a few hundred metres away.
What counts as overhead
Overhead means more than halfway up the sky (48.5 degrees or more) and below 7,000 ft, the CAA's definition of an overflight (CAP 1498). A day counts as one way when 80% of its flights used that way.
