An aircraft, which is longitudinally stable, will tend to return to level flight after a movement about which axis?
- Pitch.
- Roll.
- Yaw.
Explanation from PART66Online
Longitudinal stability is stability about the lateral axis, governing pitch. An aircraft with positive longitudinal stability tends to return to its trimmed pitch attitude after a disturbance, mainly through the restoring moment provided by the tailplane. Roll relates to lateral stability and yaw to directional stability.

Longitudinal axis = roll = lateral stability
Lateral axis = pitch = longitudinal stability
Normal axis = yaw = directional stability
Lateral axis = pitch = longitudinal stability
Normal axis = yaw = directional stability
