<DIV><FONT face=Arial size=2>When rudder is applied, it increases the lift of
the wing panel accelerated forward and decreases the lift of the wing panel
accelerated aft - resulting in differing amounts of lift being produced by the
wing panels (resulting in rotation). The application of rudder may or may
not stall the wing panel accelerated aft - and it certainly won't stall the wing
panel accelerated forward.</FONT></DIV>

<P align=left><SPAN lang=en-us><FONT face=Arial>Jim:</FONT></SPAN></P>
<P align=left><SPAN lang=en-us><FONT face=Arial>The wing is stalled when the
critical angle of attack is reached, which can happen at any airspeed,
starting from any flight attitude. This is most easily seen & felt
if you go up in a light plane and gradually work the yoke back, increasing
the angle of attack and holding altitude as airspeed bleeds off before the
stall. This can go on for many seconds. The total lift is
staying the same before the stall, but the wing doesn't stall until the
angle of attack gradually increases to the point that the critical AOA is
reached. In that example, the critical AOA will be reached at a
lower airspeed due than if the pilot had done an accelerated stall by
yanking the yoke rapidly back.</FONT></SPAN></P>

Re: Snaps</FONT></SPAN></P>
<P align=left><SPAN lang=en-us><FONT face=Arial>How do you stall a wing
that is not producing any lift, as in the case when the plane is on a
vertical up or down line?</FONT></SPAN></P>
<P align=left><SPAN lang=en-us><FONT face=Arial>My definnition of stall is
when an increase in angle of attack does not produce an increase in
lift. Another might be when the lift does not exceed the
weight. I've got to believe we know a snap when we see it and we
ought to quit trying to describe it in words.</FONT></SPAN></P>
