The stiffness does not only depend on the static stability term N _ \ beta, it also contains a term which effectively determines the angle of attack due to the body rotation.

Since the Tejas is a relaxed static stability design, it is equipped with a quadruplex airbrakes located in the upper rear part of the fuselage, one each on either side of the fin.

He eventually became a Senior Lecturer in the field of performance, stability and control of aircraft . He authored " An Introduction to the Longitudinal Static Stability of Low-Speed Aircraft " in 1966.
44.
For a tailless aircraft V _ t = 0, the neutral point coincides with the aerodynamic center, and so for longitudinal static stability the center of gravity must lie ahead of the aerodynamic center.
45.
Many aircraft have " positive " static stability to induce them to return to a straight, level flight attitude when the controls are released, maneuverability is reduced as the inherent stability has to be overcome.
46.
For a vehicle to possess positive static stability it is not necessary for its speed and orientation to return to exactly the speed and orientation that existed before the minor change that caused the upset.
47.
It follows that the centre of pressure must lie aft of the centre of gravity for static stability . x _ { cp } is the static margin and must be negative for longitudinal static stability.
48.
It follows that the centre of pressure must lie aft of the centre of gravity for static stability . x _ { cp } is the static margin and must be negative for longitudinal static stability.
49.
The ranking system that the Transportation Department now plans to use consists of one-half the track width of the vehicle divided by the height of its center of gravity, a ranking called the static stability index.
50.
Among the most significant aerodynamic changes are the enlarged leading edge extensions ( LEX ) which provide improved vortex lifting characteristics in high angle of attack maneuvers, and reduce the static stability margin to enhance pitching characteristics.
