What is the primary consequence of exceeding the critical angle of attack on a UAV's wing?

The primary consequence of exceeding the critical angle of attack on a UAV's wing is a stall, resulting in a significant reduction in lift and a sharp increase in drag. The angle of attack is the angle between the wing's chord line (an imaginary line from the leading edge to the trailing edge of the wing) and the relative wind (the direction of the airflow relative to the wing). As the angle of attack increases, the lift generated by the wing also increases, up to ....
