Aircraft noise and flight paths over Greenwich

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: observed, lowest 500 ft - night is sampled as often as day, but night traffic is light, so this is a floor and no rate can be put on it.

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.

Greenwich planning - frequently asked

Is Greenwich flood-prone?

We don't yet hold flood mapping covering Greenwich, so this page can't say how much of the suburb is flood-affected - that is a gap in our data, not an indication that the suburb is free of flood risk. Lane Cove is the authority to check for flood mapping in this area. Published flood models are held over parts of Greenwich; 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 1,500 ft. At the busiest point in the suburb about 7 aircraft a day were recorded passing over one 500 m square.
