1. AIRCRAFT TECHNICAL ENGLISH FLIGHT CONTROLS

2. THE THREE AXES There are three axes, called the longitudinal axis, lateral axis and the vertical axis CENTER OF GAVITY is the balance point of the aircraft

3. THE LONGITUDINAL AXIS The longitudinal axis runs from the nose of the A/C though the tail This axis we have the movement called “ROLL”

4. AILERONS Aileron Ailerons can be used to generate a rolling motion for an aircraft. LOCATION: Ailerons are small hinged sections on the outboard portion of a wing. MOVEMENT: Ailerons cause one wing tip to move up and the other wing tip to move down

5. THE LATERAL AXIS The lateral axis runs from wingtip to wingtip This axis we have the movement called “PITCH”

6. THE ELEVATORS Elevators Elevators can be used to generate a pitch motion for an aircraft. LOCATION: Elevators are located on the tail of the airplane attached to the horizontal stabilizer. MOVEMENT: Point the elevator up: and the nose goes up and the airplane climbs. Point the elevator down: and the nose goes down and the airplane goes down.

7. THE VERTICAL AXIS The vertical axis runs from the top to the bottom of the A/C passing through the point of intersection of the longitudinal and lateral axes and perpendicular to both axes This axis we have the movement called “YAW”

8. THE RUDDER Rudder Rudders can be used to generate a yaw motion for an aircraft LOCATION: Rudders are located on the fin of the aircraft called the vertical stabilizer MOVEMENT: The rudder causes the airplane's nose to move to the right or left

10. TRIM TABS TRIM TABS are small fixed or moveable panels attached to the rear of the ailerons, elevator and rudder. TRIM TABS are used to balance the control surface for each phase of flight

11. HIGH LIFT DEVICES High lift device are installed on aircraft to help the wing at low speed

12. HIGH LIFT DEVICES FLAPS Flaps are movable panels attached to the tailing of the wing The main purpose of the flaps is to increase lift at low speed(during take off) and increase lift as well drag (during landing) The most common type of flap is the Fowler flap

13. HIGH LIFT DEVICES SLOTS AND SLATS SLOT are openings created in the leading edge of the wing. When the angle of attack increases, air will went to break away from the wing when it nears stalling speed. The airflow though the slots will help the air flow smoothly over the wing at slower speeds SLAT are moveable on the leadings edge of the wing. When they are deployed, they form a slot thereby doing the jobs of slots

14. AIR BRAKES There are several different types of airbrakes. They are mostly used to slow down the aircraft and to help descend quicker. They also be used after landing to help slow down the aircraft after landing
