Speaking of power

[Gray E Fowler]

One more note about the 103 dB limit... dissapeared were 4 gas planes 
measured on the ground-no supersonic prop- 104, 105 106 and 108 dB!

Good for FAI being 94 dB, but 96 is plenty low. While I was Pres of my 
club we passed a noise ordinance rule, measured the same way pattern 
planes are.....limit is???? 103 dB!! And this was not politically easy, 
but at least it now stops the monster screamers and now when someone has a 
loud plane EVERYONE questions is it and we measure. 
94 dB is too low considering that an ARF trainer with a bb .46  is 95-96 
dB. Getting a club noise rule in place is good, but for us a bit late. The 
gassers already pissed off two neighbors and now the 94-97 dB plane is a 
nusiance to them even though those planes had been flying near their 
houses for 5 years without any complaints. I suggest that all clubs get 
something in place BEFORE the problem starts. We were proactive and had 
the rule voted on but not active when the first major complaint happened. 
Now it is an on going battle. And like someone else mentioned...the loud 
plane disappeared...not come back with a "real muffler"....just gone and 
that is fine with the entire Richardson club. By the way...we also banned 
props over 22" as they were a huge noise culprit.

I'll "chime" in here.  Everyone who thinks they don't have a noise issue 
should read this and pass it on the their club officers, because the 
reality is that once you get noticed you can't be quiet enough.  This 
noise thing will be much easier if we are proactive.  I know this is not 
popular, but it is reality.
