Static longitudinal stability refers to the aircraft’s ability to return to its equilibrium angle of attack, following a disturbance or perturbation. This is achieved through the application of aerodynamic pitching moments, which act to counteract any changes in angle of attack and restore the aircraft to its original position. In other words, static longitudinal stability measures the degree to which the aircraft is self-correcting, without the need for external intervention or pilot input. A well-designed aircraft will exhibit strong static longitudinal stability, providing a comfortable and safe flying experience for passengers and pilots alike.
