Good question. By keeping the nose up and increasing the angle of attack enough, deflection can push air downward, similar to how a rudder works. So its a 2nd way to get lift, different from the more efficient (lower drag) airliner airfoil using the Bernoulli effect with little or no needed angle of attack. In cruising flight that is. For climbing both would happen, but especially brute force angle of attack, with flaps.If the force on the wing is upward, why can planes fly upside down?
It's an interesting topic. Now I'm wondering about new stuff, like what about supersonic, and what about sails (both effects or just one?).
