Planes overhead in RM1
Havering, London. All 517 of its postcodes measured, January to August 2026.
From London City
Planes land and take off into the wind, so the weather decides which way London City flies, and that decides how many pass over RM1. Across its postcodes, January to August 2026:
- On a day it flies west (47% of days): up to 38 a day; of its 517 postcodes, 91 at 10 to 99, 16 on an edge, 410 under 10
- On a day it flies both ways (18% of days): up to 22 a day; of its 517 postcodes, 110 at 10 to 99, 17 on an edge, 390 under 10
- On a day it flies east (35% of days): up to 37 a day; of its 517 postcodes, 20 at 10 to 99, 39 on an edge, 458 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.

Also counted here: Heathrow, at most 3 a day over any of its postcodes.
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.
Over 4 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.
