Planes overhead in WA10
St Helens and Knowsley, Merseyside. All 1,274 of its postcodes measured, January to August 2026.
From Manchester
Planes land and take off into the wind, so the weather decides which way Manchester flies, and that decides how many pass over WA10. Across its postcodes, January to August 2026:
- On a day it flies west (70% of days): up to 2 a day; of its 1,274 postcodes, 1,274 under 10
- On a day it flies both ways (10% of days): up to 6 a day; of its 1,274 postcodes, 1,274 under 10
- On a day it flies east (20% of days): up to 13 a day; of its 1,274 postcodes, 482 at 10 to 99, 792 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 126 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.
