2. Airplane Flight: X-Plane in the Classroom

3. Control Pitch - nose moves up and down

4. Control Pitch - nose moves up and down Yaw – nose moves left and right

5. Control Pitch - nose moves up and down Yaw – nose moves left and right Roll – airplane rolls along the nose to tail axis

6. Control Stability The property of an airplane to return to its original position when disturbed by an outside force.

7. Control Stability The property of an airplane to return to its original position when disturbed by an outside force. Roll and Yaw Stability

8. Control Stability The property of an airplane to return to its original position when disturbed by an outside force. Roll and Yaw Stability Dihedral- wing angles

9. Control Stability The property of an airplane to return to its original position when disturbed by an outside force. Roll and Yaw Stability Dihedral- wing angles Dihedral provides stability

10. Control Stability The property of an airplane to return to its original position when disturbed by an outside force. Roll and Yaw Stability Pitch Stability

11. Control Stability The property of an airplane to return to its original position when disturbed by an outside force. Roll and Yaw Stability Pitch Stability Tail

12. Control Stability The property of an airplane to return to its original position when disturbed by an outside force. Roll and Yaw Stability Pitch Stability Tail Arrow analogy

13. Control Stability Airplanes, teeter-totters, and torque

14. Control Stability Airplanes, teeter-totters, and torque Torque or moment Application of force to rotate an object about a fulcrum.

15. Control Stability Airplanes, teeter-totters, and torque Torque or moment Application of force to rotate an object about a fulcrum. Tail Moment Arm

16. Control Stability Airplanes, teeter-totters, and torque Torque or moment Application of force to rotate an object about a fulcrum. Tail Moment Arm Center of Gravity Moment Arm

17. Control Stability Airplanes, teeter-totters, and torque Torque or moment Application of force to rotate an object about a fulcrum. Tail Moment Arm Center of Gravity Moment Arm Wing is the “fulcrum”
