THis is Kevin's original post.
Kevin asked:
Has anyone heard that the belly of the Ercoupe was purposely designed to
flutter and make noise as a stall warning device? And that people over the
years have put stiffeners in this area to make it stop in the believe that it
was a design and in doing so disabled the stall warning? How could the
"belly" of the plane flutter? I’d think that formed aluminum like that would
be quite rigid.
Don't think there is anything about spinning in the post. I know that Ercoupes
can and do stall, they just don't spin or come right out of it. Many planes
have a stall warning. Now that is a warning not telling the pilot he is in a
stall or spin, just a warning. I have not heard that the belly functioned as a
stall warning, if it does "Great", if it doesn't "GREAT" either way Kevin
doesn't deserve to have his post demeaned or criticized.
And doctor, over to you! Post should be read totally and not interperted as
one wishes, but as written. This forum is here to assist, not bolster one's
self esteem by demeaning someone else's innocent question that was asked hoping
to get some revelent information. I have been in a coupe that stalled and due
to incorrect rigging (my opinion ) it fell off to the right in a dive. If the
belly does vibrate as a warning when one is nearing a stall, that is wonderful
even if it was not specifically designed to do so. It would alert a distracted
pilot that he was a bit too slow.
So fellows lets read posts thoroughly and only then answer them with the desire
to help the person asking the question and not to criticize them or to
demonstrate how much more we we know than someone else.
