Where the noise comes from
Helicopters & other light aircraft
18 overflights/day (100%) · typically 900 ft
The dominant source is Biggin Hill Airport on the borough's southern edge: business jets and light aircraft arrive and depart over Bromley at around 900 ft, concentrated on weekdays. Police, medical and private helicopters add to the mix.
Light-aircraft counts are tracked overflights only — many training and private aircraft carry no ADS-B transponder, so true numbers are higher.
