Therefore, the aircraft is longitudinally stable.

-0.1 < 0

An aircraft has a static margin of 0.2 and a pitching moment coefficient of -0.05. Determine the aircraft's longitudinal stability. Flight Stability And Automatic Control Nelson Solutions

where m is the pitching moment and α is the angle of attack. Therefore, the aircraft is longitudinally stable
