Hi Greg,

The 69db as stated in my noise certificate are less than meaningless to
me.
I do not know if you are familiar with these certificates but they are
used to calculate the landings fees in some countries.
This and the MTOW determines the basic fee.
To keep the noise(and the complaints) down most airfields ask a higher
fee when landing after 19:00(2xbasic fee), on saturdays(2x),
sundays(3x) and official holidays(3x) during the summer
period(apr~okt).
So, most people think twice before practising circuits during these
times.

But you are right that there are different kinds of noise and aircraft
sound can be a bit annoying.

I've been to a meeting with complainers, some of them are reasonable
people who think that together we can come to a sensible solution(my
idea too).
The most(that I've met) however are fanatics that will not rest before
the airfield is closed.
Those are the ones that go to court for about anything (even
vaguely)related to the field.

I had a good laugh though.
Some examples from complaints against our field:
-Complaints about fast small yellow planes that make this irritating
whining sound.
Airforce trainers from a nearby base.
-The jump plane has a diesel engine now, so it makes more noise.
No, it is 4db less than before.
Etc etc.

Anyway, I think I'm nice to our neighbours.
I allways reduce power at reaching 200~300ft AGL(the other end of our
2500ft runway)
Climbing at 75% and not overflying populated areas, parks, beaches,
etc. when possible.
