07. Fixed Wing Control Surfaces

More Control Surfaces

The ailerons, elevators, and rudder are used to control roll, pitch, and yaw. But these aren't the only control surface you'll find on fixed wing vehicles.

Flaps

Flaps are mounted on the interior section of each wing and are used to reduce the "stall speed" of an aircraft by increasing the amount of lift the wing generates. They are typically used by commercial jets during take-off and landing.

Spoilers

Spoilers are used on low-drag aircraft to reduce lift by disrupting airflow. Glider pilots use spoilers when they want to lose altitude without gaining too much speed.

Slats

Slats are mounted on the leading edge of wings. When deployed, they allow the aircraft to operate at lower speeds.

Air Brakes

Air brakes slow the aircraft down by increasing drag. Spoilers can act as air brakes, but they also reduce lift. Air brakes are often mounted on the side of the fuselage to minimize their effect on lift.
