Which action impairs aircraft lift at high angles of attack?

💡 Explanation

Boundary layer flow separation reduces lift sharply because the airflow detaches from the wing surface, eliminating pressure differential. Therefore, lift diminishes rather than increasing, because turbulent flow reduces lift more than laminar flow.
