Longitudinal directional stability refers to the ability of an aircraft to maintain its heading when disturbed by external forces, such as turbulence or control inputs. It is achieved through proper design of the aircraft's aerodynamic characteristics, including the location of the center of gravity relative to the center of lift. Strong longitudinal directional stability helps pilots maintain control of the aircraft in various flight conditions.
