2. Airplane Flight: X-Plane in the Classroom

3. Four Forces Of Flight Weight Lift Drag Thrust

4. Topics Lift Stall Theories explaining lift

5. Lift as a force

6. Lift results from a difference of air pressure along the wing.

7. Lift as a force Lift results from a difference of air pressure along the wing. Lift is up and perpendicular to the flight path.

8. Lift as a force Lift results from a difference of air pressure along the wing. Lift is up and perpendicular to the flight path. Lift is sensitive to both:

9. Lift as a force Lift results from a difference of air pressure along the wing. Lift is up and perpendicular to the flight path. Lift is sensitive to both: Air speed over the wing

10. Lift as a force Lift results from a difference of air pressure along the wing. Lift is up and perpendicular to the flight path. Lift is sensitive to both: Air speed over the wing Angle of attack of the wing

13. Lift as a force Lift results from a difference of air pressure along the wing. Lift is up and perpendicular to the flight path. Lift is sensitive to air speed and angle of attack Lift Vectors

14. Lift as a force Lift Vectors Green – vertical lift

15. Lift as a force Lift Vectors Green – vertical lift Yellow – horizontal lift (very small)

16. Lift as a force Lift Vectors Green – vertical lift Yellow – horizontal lift (very small) Red - drag

17. Lift Stall Airplane begins to fall from the sky. Results from not enough air flowing over the wings.
