3.1 — Static Stability & Control Surfaces

Key insights

Key ideas from this lesson:

• Static stability is the tendency to return to equilibrium after a disturbance; dynamic stability is how the motion evolves over time.
• CG position governs longitudinal stability — forward CG increases it.
• Elevator pitches, ailerons roll, rudder yaws: the three primary control axes.
• Trim systems let the aircraft hold attitude without constant control force.
