Planes overhead in IG4
Redbridge, London. All 135 of its postcodes measured (3 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 Redbridge, council by council.

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: Stansted, at most 1 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.
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.
