1. Boy Scouts Aviation Merit Badge Control Surfaces

2. Primary Control Surfaces Ailerons Rudder Elevator

3. Aileron The ailerons are located near the rear end of the wing tip

4. Aileron controls the roll of the plane Longitudinal axis

5. Elevators The Elevators are located on the horizontal stabilizer of the tail

6. Elevators controls the pitch of the plane Lateral axis

7. Rudder The rudder is located on the vertical stabilizer of the tail

8. Rudder Vertical axis controls the yaw of the plane

9. Control Surfaces Aileron – controls the roll of the plane Aileron – controls the roll of the plane Elevator – controls the pitch, or the up and down, movement of the plane Elevator – controls the pitch, or the up and down, movement of the plane Rudder – controls the yaw, or side to side, movement of the plane Rudder – controls the yaw, or side to side, movement of the plane

10. How the Control Surfaces Work Together for Flight Take off down the runway Take off down the runway – Aileron - level – Elevator – neutral – Rudder – neutral

11. Control Surfaces Straight Climb Straight Climb – Aileron - level – Elevator - up – Rudder – neutral

12. Control Surfaces Level Left Turn Level Left Turn – Aileron – left up, right down – Elevator – neutral – Rudder – left rudder

13. Control Surfaces Climbing left turn Climbing left turn – Aileron – left up, right down – Elevator – up – Rudder – left rudder

14. Control Surfaces Straight descent Straight descent – Aileron - level – Elevator - down – Rudder – neutral

15. Control Surfaces Landing Landing – Aileron - level – Elevator - down – Rudder – neutral
