What is the result of exceeding critical angle of attack?

When the critical angle of attack is exceeded, the airflow over the wing begins to separate from the upper surface. This phenomenon leads to a significant loss of lift and an increase in drag, ultimately resulting in what is known as a stall. The critical angle of attack is the maximum angle at which the wing can maintain smooth airflow. Beyond this point, the wing can no longer generate sufficient lift to support the weight of the aircraft, causing it to lose altitude and control momentarily. Understanding this concept is crucial for pilots in order to maintain safe flight operations and avoid situations that lead to stalling.
