<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>

<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>
