The angle of attack is dependent on the 'relative wind' and has nothing to do with the wing chord reference to speed, attitude of the aircraft/airframe or anything else other than the relationship of the aerodynamic chord of the wing relative to the "relative wind". There are a number of publications, including FAA stuff, that explain the concepts (I bet Mark L can chime in here too) :)

I am not an engineer but I always understood if there is not enough air across the wing it is stalled. so what does the angle have to do with no air across the wing? I know if you pull up and block the top of the wing it will stall. I have stalled the wing at 105 mph and the tail at 115 mph. For your information it was not on purpose and I do not suggest it. The wing stall did not do much I just let it fall off on one side and after the second spin I pulled it out. The tail stall scared the **** out of my wife and I and she said not to do that ever again, Like I would. --- On Wed, 4/6/11, Virgil N. Salisbury <virg...@bellsouth.net> wrote: From: Virgil N.

If it is less than~13 Degrees, Then full stall is NOT possible.
