Where the noise comes from

Helicopters & other light aircraft

5 overflights/day (100%) · typically 1,600 ft

The low traffic overhead is almost entirely light aircraft and helicopters on the North Downs transit routes, typically around 1,600 ft.

Light-aircraft counts are tracked overflights only — many training and private aircraft carry no ADS-B transponder, so true numbers are higher.
