Aircraft noise and flight paths over Cremorne

Two different things, kept apart on purpose. The ANEF contour is the planning instrument - a forecast published per airport that planning schemes use to control noise-sensitive development. Observed overflight is what a sampled aircraft-tracking feed actually recorded over the suburb - where aircraft flew, how low and how often.

Night movements: not established - night is sampled as often as day, but too few night flights have been seen here to conclude either way.

Traffic is sampled rather than watched continuously, so every figure is a floor: aircraft not captured between samples are not represented. Rates are per 500 m square - the busiest square in the suburb, not a count of flights over the suburb - and a square is only rated where enough traffic was seen to measure it. Altitudes are above mean sea level. Flight paths change with runway use, weather, season and airspace design. This is a record of observed traffic; it is not a noise contour and not a planning control.

Cremorne planning - frequently asked

Is Cremorne flood-prone?

Published flood models are held over parts of Cremorne; the free check on the Flood Model Report page says whether one reaches a given address.

The lowest measured aircraft was at 500 ft, with an average of 5,000 ft. At the busiest point in the suburb about 6 aircraft a day were recorded passing over one 500 m square.
