Noise, a very outdated stance given todays planes are much quieter than those of last century
Exactly! Anyone living under the flight path today knowingly bought / rented there, as its been an airport for 105 years.
Further when 3rd runway opened, government spent a motza of tax payer funds providing grants for home owners to better noise insulate their homes.
Western Sydney Airport wont have a curfew yet some claim will eventually have many more people living under the flight path in homes that didn't get free insulation. Just a case of continued NIMBYism.
I lived directly under the SYD flight path for years and my current home occasionally gets fly-over noise when weather causes non usual approaches to be used. I can say from experience you cant really hear the noise inside a modern home, only when outside in yard.
It should be a non issue and removed for flights approaching from the water or at the very least reduced to 12am - 5am only. They allow flights at 6am but unless flying for work Id usually be asleep at 6am but wide awake at 11:30pm.
