Title: Define longitudinal stability.
Course: Aircraft Pilot Training I (20053-I) > Section: Explaining the Aerodynamics of Flight

Definition should include the following concepts:

- There is a range of CG limits acceptable for an aircraft.
- Longitudinal stability is the quality that makes an airplane stable about its lateral axis.
- Longitudinal stability involves the pitching motion as the airplane’s nose moves up and down in flight.
- A longitudinally unstable airplane tends to dive or climb progressively into a very steep dive or climb, or even a stall.
- A longitudinally unstable airplane becomes difficult and sometimes dangerous to fly.

Process/Skill Questions:

- How is the range of CG limits acceptable for an aircraft related to weight and balance?
- What is an airplane's lateral axis?
