Planes overhead in NW11
Barnet, London. All 833 of its postcodes measured, 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 NW11. Across its postcodes, January to August 2026:
- On a day it flies west (56% of days): up to 98 a day; of its 833 postcodes, 833 at 10 to 99
- On a day it flies both ways (15% of days): up to 93 a day; of its 833 postcodes, 833 at 10 to 99
- On a day it flies east (29% of days): up to 71 a day; of its 833 postcodes, 833 at 10 to 99
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.

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.
