Hi,

plane stalls really when i pitch down.
I'm not sure to know exactly how it have been determined but i try to
explain.
A plane stalls in my case if liftcoefficent for a cambered airfoil with a
plan trailing edge flap is equals to zero.
Flaps to calc. liftcoefficient are landing flaps and ailerons.


At a low enough angle of atack (angle between the wing and the air flow)
lift will go to zero - is this what's happening?

At a high angle of atack (pitch up) when a wing "stalls" the lift is reduced
but does not generally go to zero while drag increases a lot.
