I am a G.A pilot and I live under a flight path close to an airport. I deal with noise complaints for an airport and there is a lot to be said about how airfields deal with the complainant. If the complaint is not dealt with in the correct way then the complainer will come back again and again and cause more issues. I take a proactive approach to the community surrounding the airport and I have found that if you are open with your operation then the complaints get curbed quickly. If you can demonstrate that you do as much as you can (as far as practicable - noise preferred routings etc) then people tend to be more satisfied. Everyone will agree that NPR's are a bit of a pain in the @rse to fly but they are a better compromise than losing all flying rights.
If airfield operators take the stance that these people are just a pain and treat them with contempt then this approach will exacerbate the situation. Give out as much information as possible so people are informed.
