face=Arial color=#0000ff size=2>> Just to stir the pot a little
further..<BR>> <BR>> I'm not sure a contemporary pattern plane can
generate enough pitch rate to reach critical angle of attack and properly
perform a snap roll. I think it's far more likely that we're seeing nothing but
a heavily yawed aileron roll, with the pitch break only being shown to judges to
convince them there is actually a stall happening, when in fact there is not.
<BR>> <BR>> If a snap cannot occur using ONLY elevator and rudder, then
the wing is not stalling. Aileron inputs into a snap actually inhibit flow
separation, as the inboard wing angle of attack is drastically reduced, and the
outboard wing AoA is drastically increased. <BR>> <BR>> But since there is
no way to actually determine what is happening aerodynamically on an F3A
airplane, the best a pilot can do is fly the airplane to what the judges expect
to see based upon the rules. It really doesn't matter what the control inputs
are if the airplane LOOKS like it's doing the right maneuver.<BR>>
