Brownlow Hill sits under Camden Airport's circuit and training traffic — light aircraft and gliders working low over the valley through daylight hours. Camden is not a tracked airport, and many of its aircraft carry no transponder, so true numbers run well above the tracked count.
Light-aircraft counts are tracked overflights only — many training and private aircraft carry no ADS-B transponder, so true numbers are higher.
