Northmead hears traffic from 2 distinct sources:
Sydney Kingsford Smith Airport
live map →22 overflights/day (90%) · typically 4,600 ft
Northmead hears a high mix of arrivals descending from the north-west and departures climbing out, without a single defining corridor. The altitude keeps individual aircraft soft; the trade-off is that some stream or other is passing through most of the day.
Helicopters & other light aircraft
2 overflights/day (10%) · typically 600 ft
Around 2 low overflights a day come from aircraft not operating at a tracked airport — helicopters, seaplanes and light aircraft transiting the area. Light-aircraft counts are tracked overflights only — many training and private aircraft carry no ADS-B transponder, so true numbers are higher.
