Constraint readout

Elevation hillshade with street names, clipped to Gloucester's boundary, with the flood, bushfire and environmental overlays drawn on top. Amber hatching is the published aircraft noise (ANEF) contour.

Aircraft noise and flight paths over Gloucester
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.
Inside an aircraft noise contour
70% of the suburb's land sits inside a published ANEF or airport-environs contour. Contours vary street by street, so whether a particular lot is inside one needs a property-level check.
Contours held
- NSW planning (EPI) airport noise
Observed overflight - sampled 4 Sep to 26 Sep 2026
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.
