[There seeming are many] relatively new flight patterns over Oahu - all small aircraft and helos now fly over our house separated by minutes. [We live in Manoa.]
[How do I file a complaint about this and is there a group I can join] to fight and get pattern changed?
Quieter O'ahu Response:
Thank you for you email. We hear often from impassioned residents as yourself about the growing assault on our quality of life by low flying aircraft, and tour helicopters in particular.
We've added you to distribution for our aperiodic emails on noise and related issues. But to your specific issue, let me point you to our website at this address: https://www.quieteroahu.com/reporting-noise-violations.html
At that link you will find a link to the current O'ahu Noise Reference Manual. While inadequate in terms of explaining how to take action on aircraft issues, it at least provides contact information and explains the current process. Too, at the bottom of our linked page, you'll find info on a relatively new organization, Airnoise.io who has begun a program of identifying sources of aircraft noise and reporting them to the FAA. Problem: they do not at this time cover O'ahu. We recommend that you might want to engage with Airnoise.io and encourage them to extend their current program to cover O'ahu due to the many problems residents are experiencing with aircraft noise in our congested and already noisy environment. One more voice could be the tipping point.
Thank you again for your email. Without referencing your personal information we will post to our Noise Blog for the benefit of other visitors to our site.
