How does the use of flaps impact an aircraft's stall speed?

Using flaps on an aircraft during flight significantly alters its aerodynamic characteristics, specifically affecting stall speed. When flaps are deployed, they increase the wing's camber and surface area, enhancing lift at lower speeds. This increased lift allows the aircraft to maintain controlled flight at slower airspeeds, effectively lowering the stall speed.

When flaps are extended, they change the airflow over the wing and induce a higher angle of attack before reaching the critical angle, whereas without flaps, the wing might reach its stall speed at a higher airspeed. This means that the aircraft can operate safely at slower speeds when flaps are deployed, making them particularly useful during takeoff and landing phases when slower speeds are critical for safe operation.

Therefore, the use of flaps is essential in reducing stall speed, providing pilots more control over their aircraft, especially in critical phases of flight.
