Why so we concentrate more on longitudinal static stability rather than the lateral and directional stability of planes?


An aircraft’s longitudinal static stability is the stability of its pitch. Pitch is the up and down motion of an aircraft. Lateral stability of an aircraft is the stability of its roll. Roll is the side to side motion of an aircraft. Directional stability is the stability of an aircraft’s yaw. Yaw is the left and right motion of an aircraft. The longitudinal static stability is important for pilots to determine if they can easily control the pitch of an aircraft in flight. Thus, pilots focus more on the longitudinal static stability over the lateral and directional stability.
