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.
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.
