Planes overhead in EN5
Barnet, London. 1,018 of its 1,045 postcodes measured, the ones in 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 EN5. Across its postcodes, January to August 2026:
- On a day it flies west (56% of days): up to 34 a day; of its 1,018 postcodes, 180 at 10 to 99, 838 under 10
- On a day it flies both ways (15% of days): up to 36 a day; of its 1,018 postcodes, 1,018 at 10 to 99
- On a day it flies east (29% of days): up to 57 a day; of its 1,018 postcodes, 1,018 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.
