If a plane is flying, its wing must be generating lift.  = Does a wing generate lift at a zero degree angle of attack?

<= font size=3D"2">I thought that there must b= e some positive angle of attack in level flight.  Am I wrong about thi= s?
=
And if I = am right, shouldn't the angle of attack be set to some small positive numbe= r?

Tom,
 
Interesting.  The wing has wash out so different parts of the win= g are=20 at slightly different AOAs (think propagation of stall).  The design h= as=20 the longeron at zero degrees at cruise, flaps at reflex (think chord line f= rom=20 leading edge to flap TE).  Even average angle of incidence doesn't wor= k=20 because of wing/flap design.  Why not use zero, 1 or 2?

>=20 Folks

I am about to setup a g3x in my 360.  I was wondering = if=20 anybody could tell me what the typical cruise angle of attack might=20 be

Thanks

Tom
