Another approach to convince municipalities to continue to operate
their airports is to make them aware of the FAA's imminent intent to
implement the Small Aircraft Transportation System*.

But this is one of the reaons municipalites want to close the
airports... residents are afraid of jet noise. And they do have a point.

Ahhh... No they don't.
It's a point based on ignorance as today's small jets are quieter than
many older prop planes and pretty much on par with most of the newer
prop planes. No, many can't match one of the new 172s, but they do a
good job.

Now, when you get up to the Falcon 900 you are pretty much reaching
the break even point compared to an old Bonanza with a two blade prop,
but the smaller jets with turbofans are much quieter. The don't burn
all the grass off the end of the runway when they run up the engines
either. That 900 pretty much cleaned the grass from the end of the
runway to the fence by the road. Good thing it was green grass and
not dry. :-))

Here the residents were afraid if we lengthened 18/36 and 06/24 to
4000 they'd be inundated with jet noise. What they didn't realize was
we have a number of jets in and out and they never notice then. What
we couldn't convince them was on 18/36 going from 3000 to 4000 feet
would make it quieter. On a hot day I'm only a few hundred feet
over their heads, but at least I went to a 3-blade prop. When I had
the 2-blade they used to complain I was rattling the dishes in the
cupboards and I have no doubt I was.

If the City Council members choose to deprive their city's residents
of the means of shuttling to the region's international airport so
that another strip mall can be built, that is their prerogative, but I
wouldn't re-elect them. :-(

And today's smaller turbofan powered aircraft aren't significantly
more noisy than piston powered aircraft especially when you consider
the shorter time they are nearby as they climb out on departure.
