Arrivals during peak periods
During peak periods at Sydney Airport the parallel runways will always be used because using both runways at the same time allows the most aircraft to be moved through the airport.
This means that, when the parallel runways are being used in a southerly direction (south flow) during peak periods, your area will experience aircraft noise.
Peak periods tend to be 7am to 11am and 3pm to 8pm, but may also extend beyond these hours.
