Aircraft noise and flight paths over Seventeen Seventy
The ANEF contour is a published planning forecast and observed overflight is what a sampled tracking feed recorded - neither describes any individual property.
Observed overflight - sampled 4 Sep to 7 Nov 2026
typical observed square 0 a day
Night movements: not established - night is sampled as often as day, but too few night flights have been seen here to conclude either way.
How this is measured
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.
