Planes overhead in N4

Haringey, Hackney and Islington, London. All 836 of its postcodes measured (35 PO boxes and other large-user postcodes left out), January to August 2026.

For Heathrow's expansion consultation, open until 22 December 2026: the planes over Hackney, the planes over Haringey and the planes over Islington, council by council.

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 N4. Across its postcodes, January to August 2026:

Each sector's bar splits its postcodes by how many planes pass over them a day; the figure above it counts those in the busiest band the sector reaches. The list above gives the whole district's counts.

Also counted here: London City, at most 1 a day over any of its postcodes.

3 of its postcodes have a position ONS estimates, so their figures may be for a spot a few hundred metres away.

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. PO boxes and other postcodes for organisations that receive a lot of post are left out: they sit at a delivery office or a business, not at homes.
