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.
The shape of the fuselage and fin improve longitudinal stability.

Yes, the traffic system is a major factor in every social system as it affects the flow of people, goods, and services within a community. It influences everything from urban planning to economic development and quality of life for residents. Understanding and managing traffic is essential for ensuring the efficient functioning of society.
The longitudinal stability of an airplane is primarily determined by the location of the center of gravity (CG) in relation to the aerodynamic center of the wing. If the CG is in front of the aerodynamic center, the airplane tends to be stable. If the CG is too far behind the aerodynamic center, the airplane can become unstable. Pilots use the elevator control surface to adjust the pitch and maintain longitudinal stability.
Directional stability refers to a car's ability to maintain a straight path without constant input from the driver. It is influenced by factors such as suspension design, tire grip, and aerodynamics. A car with good directional stability will track straight and not easily drift or wander off course.
The longitudinal arm of an R22 helicopter is the distance from the center of gravity to the main rotor shaft. It is an important parameter for calculating balance and stability of the helicopter during flight.
