Lateral Stability & Control

Lateral Static Stability

1. What is the effect of wing dihedral on the lateral stability of an airplane?
2. What is the effect of wing sweep on the lateral stability of an airplane?
3. Does it make a difference if the sweep is aft or forward?
4. How do we usually compensate for the sweep effect on high performance airplanes?
5. What is the effect of flaps (employed during takeoff and landing) on the lateral stability of an airplane?
6. What is the effect of the fuselage on the lateral stability of an airplane?
7. What is the effect of the vertical stabilizer on the lateral stability of an airplane?
8. What is the effect of a dorsal fin on the lateral stability of an airplane?
9. What is the effect of a ventral fin on the lateral stability of an airplane?
10. What is the effect of wing placement (high vs. low) on the lateral stability of an airplane?

Lateral Dynamic Stability

1. Describe damping in roll.
2. Describe autorotation.
