Harrow, Brent and Barnet, London. 846 of its 847 postcodes measured, the ones in Harrow, Brent and Barnet, January to August 2026.
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 HA7. Across its postcodes, January to August 2026:
- On a day it flies west (56% of days): up to 23 a day; of its 846 postcodes, 446 at 10 to 99, 400 under 10
- On a day it flies both ways (15% of days): up to 31 a day; of its 846 postcodes, 846 at 10 to 99
- On a day it flies east (29% of days): up to 27 a day; of its 846 postcodes, 843 at 10 to 99, 3 under 10
The table counts the postcodes of each sector by how many planes pass over them a day: 100 or more, 10 to 99, or under 10.

2 of its postcodes have a position ONS estimates, so their figures may be for a spot a few hundred metres away.
Over 5 of its postcodes, other flying passes too, from airfields, helicopters and airports we cannot check against official counts, so few planes from the airports we count does not mean a quiet sky there.
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.
