Control Surfaces Work ?
Control surfaces are the moveable outer surfaces of an airplane. These surfaces control the flow of air over the various sections of the aircraft causing it to move in different ways. Inside the airplane, pilots control the movement of the surfaces with their hands or feet by pushing, pulling or turning the controls to make the airplane move in the proper manner.
By learning the names and functions of the various surfaces, you will appreciate the construction, design, and aerodynamics of the airplane.
AIRPLANE
An airplane is a vehicle heavier than air, powered by an engine, which travels through the air by the reaction of air passing over its wings.
FUSELAGE
The fuselage is the central body portion of an airplane, which accommodates the crew and passengers or cargo.
COCKPIT
In general aviation airplanes, the cockpit is usually the space in the fuselage for the pilot and the passengers: in some aircraft it is just the pilot’s compartment.
LANDING GEAR
The landing gear, located underneath the airplane, supports it while on the ground.
WINGS
Wings are the parts of airplanes which provide lift and support the entire weight of the aircraft and its contents while in flight.  The cross-section of the wing is an airfoil.
PROPELLER
A propeller is a rotating blade located on the front of the airplane. The engine turns the propeller which most often pulls the airplane through the air,  The propeller is also an airfoil.
FLAPS
Flaps are the movable sections of an airplane’s wings closest to the fuselage. They are moved in the same direction (down) and enable the airplane to fly more slowly.  By lowering the flaps, the pilot is increasing the camber of the wing which increases the distance air must travel over the top of the wing.  This produces more lift which allows the aircraft to fly at lower speeds.  This is desirable for landings.
AILERONS
Ailerons are the outward movable sections of an airplane’s wings which move in opposite directions (one up, one down). They are used in making turns.  The movement of the ailerons also changes the camber of the wing at the outer edges.  Since the move in opposite directions, one wingtip produces more lift while the opposite wingtip produces less lift.  This imbalance causes the aircraft to bank.
RUDDER
The rudder is the movable vertical section of the tail which controls lateral movement.
HORIZONTAL STABILIZER
The horizontal stabilizer is the horizontal surface of the aft part of the fuselage used to balance the airplane.  It is an upside down airfoil which exerts a downward force to compensate for the nose heavy configuration of most aircraft.
ELEVATOR
The elevator is the movable horizontal section of the tail which causes the plane to move up and down.
