I bet you guys would be of the same opinion if a new flight path suddenly popped up over your home, decreasing it's value and your quality of life.
If opposition to more aircraft noise in congested areas drove voters to the Greens well that's democracy in action, but you'll also find the LNP members in Brisbane
last month acknowledged increased noise in the city is an issue and vowed to make changes to decrease noise.
The real problem is most Australian airports have an approach or departure track over a large proportion of that city's urban area. Brisbane 01, Sydney 16, Adelaide 23 stand out. Great view out the window but you're going to annoy a lot of people underneath. If we had long term foresight in this country we'd plan and build airports some distance from the urban area serviced by fast rail and road links, make greater use of RNP for curved approaches and get cracking on better insulation materials like graphene that'd take engine noise down by quite a few decibels.
