soooooooo right !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I've been trying to get this
through to the powers that be for the last 3 years.</FONT></DIV>
<DIV><FONT face=Arial size=2>Nat, I particularly like that reference to the rate
of rotation relative the normal aileron speed of rotation. That's a teriffic
criterion and should probably be included in the book.(Yeah, I know, I know you
guys, before you go gettin' all huffy, there are snaps done at different rates
of rotation, go get yourself another piece of watermelon, it's hot
today).</FONT></DIV>

<DIV>Agreed, and therefore the CG of the plane can't travel a straight line.
</DIV>
<DIV> </DIV>
<DIV>The "break" will cause the the wing to go through its maximum lift AOA.
That alone will cause the path to deviate. Once "stalled" the wing is still
lifting, 3D flying proves that. </DIV>
<DIV> </DIV>
<DIV>I recently flew a plane that was being video taped, and performed several
snap rolls coming straight towards the camera. When the playback was slowed
down, it was apparent the plane was NOT following a straight path. The plane
obviously stalled, and autorotated, but the path was a spiral. </DIV>
<DIV> </DIV>
<DIV>I would like for someone to produce a video of a snap roll, flown
straight towards or away from the camera, where the CG stayed on a
straight path.</DIV>
