Harrow and Hillingdon, London. 1,093 of its 1,094 postcodes measured, the ones in Harrow and Hillingdon, 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 HA5. Across its postcodes, January to August 2026:
- On a day it flies west (56% of days): up to 4 a day; of its 1,093 postcodes, 1,093 under 10
- On a day it flies both ways (15% of days): up to 14 a day; of its 1,093 postcodes, 643 at 10 to 99, 450 under 10
- On a day it flies east (29% of days): up to 11 a day; of its 1,093 postcodes, 97 at 10 to 99, 996 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.

Over 74 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.
