An airplane pilot must be very careful to maintain a proper angle of attack during flight because
A) too low an angle of attack will cause the Bernoulli effect to be pre-empted and hence the plane will never take off.
B) too steep an angle of attack will cause too much energy to be wasted in friction with the air via laminar flow.
C) too low an angle of attack will cause turbulent flow around the wing and hence stalling.
D) too steep an angle of attack will cause turbulent flow around the wing and hence stalling.
