<DIV><FONT face=Arial size=2>You're both right on regarding noise footprint.
Probably the biggest issue with the large gassers, and not necessarily IMAC.
</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'm involved in helping a club with noise
abatement to avoid upsetting the neighbors. The sound levels at the property
boarders have been measured, typical and local laws reviewed, maximum sound
levels and methods of measurement established, and club rules enacted.
Enforcement is active and peer pressure working - there's even a bit of
competition to have the quietest set-up. This part is working
great.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>However, most or the folks flying the 100 - 150cc
powered airplanes are relatively new flyers (none compete). While they're
generally competent flyers, or fly with assistance, they have no appreciation
for distance. It's typical for these folks to fly a 30-40% airplane at a
distance so that it looks like a 40 size trainer at 200 yards! Downwinds on
landing may be 300 yards away. They don't realize how far away the
airplane really is and it takes continuous "coaching" to keep these things
closer - enough that it creates "friction". The bigger footprint alerts
neighbors, regardless of noise (noise doesn't help) and raises their
(justifiable) safety concerns.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Along comes a competition flyer practicing rollers
and he becomes the example that the distance is OK, and enforcement becomes even
more difficult. </FONT><FONT face=Arial size=2> I agree that rollers
are neat maneuvers and that they simply don't fit within the "smaller footprint"
concept. Dean, I like your proposal that they be replaced with rolling loops -
keeps the complexity and solves the distance problem. Have you suggested this to
Bob Skinner (F3A Subcommittee Chair)? We're our own worst enemy -
rollers can be flown much tighter, but no one does that - no wow factor! My
alerts that the pattern rules don't provide a distance exception for rollers
only resulted in a quasi exception. </FONT></DIV>

<DIV>Dean,</DIV>
<DIV> </DIV>
<DIV>Right on point. I've been involved with a flying field lost due to noise,
and was also involved in a successful fight to keep a field open after
neighbor's complaints. Better to be reasonably quiet in the first place. Once
you have upset the neighbors to the point that they start to complain, their
"threshold of pain" becomes much lower. Once they have made up their minds
they don't like you, they probably never will like you again, regardless of
what you do.</DIV>
<DIV> </DIV>
<DIV>The one - maybe the only - big negative that I see with IMAC is the noise
level along with the noise footprint. But, you know, 20 years ago you
could say the same thing about pattern. I just hope the guys in IMAC (and
giant scale in general) can learn from the mistakes made in pattern --
BEFORE flying fields are lost for both camps!</DIV>

<DIV>Hi Dave,<BR>What I hope we are saying here, is that being smart and
making our aerobatic planes quiet is good for the continued survival of both
events. Of course, if flyers with large, loud, and far-away 40% planes lose
all our practice fields and practice sites ...<BR><BR>This is just how the
West Windsor contest in Jersey became a "first annual and only ever"
event.<BR>Sadly, I have to say that two or three IMACers joined the club,
and within a few months, we had no Pattern Contest, a 6:00 P.M. weekday
curfew on wet power, and neighbors who are now very aware of our existence.
Being noticed ain't always a good thing! Smart noise abatement programs are
aimed at preventing that first complaint. Once it happens, it's almost too
late.<BR>..............................</DIV></BLOCKQUOTE>
