2 of its postcodes have a position ONS estimates, so their figures may be for a spot a few hundred metres away.
Over 175 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. 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.
