Noise (was A question only a newbie would ask)

The majority of the noise generated by piston planes isn't engine noise, but
propeller noise.

The thing that gets me are the dildos^H^H^H^H^H^Hfellow pilots with CS props
who set them to maximum RPM during approach. That makes their planes more
than twice as loud as the fixed-pitch planes (who are around 1500 rpm on
approach), and while I love hearing all the small planes flying over my
house, I'm worried that my neighbours might someday lose their goodwill and
patience.

I have no issue with max RPM on takeoff, of course. Most planes climb more
steeply than they approach, so the noise doesn't last long in any case.


All the best,

The word "decibel" has the most interesting etymology.

-heard Mary fly over, and it makes a huge difference in decibel level.

A very knowledgeable FAA engineer/test pilot told me that he would not
do a single-engine go-around in anything smaller than a KingAir...and
he "wrote the book" on zero-sideslip.


What does your friend do if he's in a single and tower says, "Go Around!" ?

I have learned to hide when the AeroShell T-6 team takes off to do their
demos. I know RPM is HP, but man, how about turning the RPM back just a
few
hundred. They are painful to listen to, even verging on nauseating!
(IMHO)

Funny -- I LOVE the way those T-6s roar past!

They've got 'em set up specifically to make lots of noise and smoke -- in
the finest airshow tradition...

Roar = good. Screech of prop tips = painful!

Never heard prop tips screech. The T-6 gives you two sonic booms for
every revolution. OTOH so does a Bonanza with a 2-blade prop.

You mean you did not install deer whistles on your prop tips?
