Using flaps _____ the stalling AOA.

Using flaps decreases the stalling angle of attack (AOA). When flaps are deployed, they increase the camber and surface area of the wing, which alters the airflow characteristics over the wing. This modification enhances the lift generated at lower speeds and allows the aircraft to maintain lift at a lower angle of attack compared to a wing without flaps.

As a result, the aircraft can reach a stall condition at a lower angle of attack due to the improved airflow and lift characteristics. This capability is critical during takeoff and landing phases, as it enables pilots to fly at slower speeds while still safely controlling the aircraft. The deployment of flaps thus effectively enhances the wing's performance, directly influencing the stalling behavior and allowing for safer operation in critical flight phases.
