2. Around the lateral axis, therefore stability of the longitudinal axis.

3. Pitch stability.

4. Horizontal Stabilizer mounted at slight downward angle, to help recover from stall naturally.

5. Lateral

6. Around the longitudinal axis, therefore, stability of the lateral axis.

7. Roll stability.

8. Controlled by wing dihedral. (Upward angle of wing, from root to tip)

9. High wing generally have less dihedral than low wing.

10. On a high wing, the CG is below the wing; on a low wing, the CG is above the wing.

11. As wing moves down, relative wind comes from lower angle, which increases angle of attack.

12. In a roll, downward wing gets higher angle of attack, which creates more lift. Opposite on up wing.

13. Directional Stability

14. Around the vertical axis

15. Yaw stability

16. To be directionally stable, aircraft must have more surface area behind the CG than in front of it. (Think: Weathervane)

17. Controlled by vertical stabilizer

18. Wing sweepback affects directional stability. (High speed aircraft)

19. Dutch Roll-Roll and yaw combined, side to side.

20. Yaw Dampers on rudder to combat this.
