What happens if a pilot exceeds the aircraft's critical angles of attack?

When a pilot exceeds the aircraft's critical angles of attack, the aerodynamic lift generated by the wings begins to decrease significantly, leading to a stall condition. The critical angle of attack is the maximum angle at which the wing can maintain smooth airflow over its surface. Beyond this angle, airflow separates from the upper surface of the wing, causing a dramatic loss of lift.

In a stall situation, the aircraft may not respond as expected to control inputs, and recovery actions must be initiated to restore normal flight. Hence, understanding the critical angle of attack is vital for pilots to avoid stalling during maneuvers, especially at lower airspeeds or during steep turns. This principle is a fundamental aspect of flight safety and aircraft handling.
