Limit of Positive Stability — or LPS is the angle at which a boat will no longer stay upright but will capsize becoming inverted. It is also known as the Angle of Vanishing Stability or AVS. For example, if a boat with an LPS of 120 degrees rolls past this point it will… … Wikipedia
Stability derivatives — are a means of linearising the equations of motion of an atmospheric flight vehicle so that conventional control engineering methods may be applied to assess their stability.The dynamics of atmospheric flight vehicles is potentially very… … Wikipedia
Positive feedback — Alarm or panic can spread by positive feedback among a herd of animals to cause a stampede. Positive feedback is energy taken from the output of a system and reapplied to the input, which is phase congruent with the input signal. A system… … Wikipedia

Longitudinal static stability — is important in determining whether an aircraft will be able to fly as intended. Static stability As any vehicle moves it will be subjected to minor changes in the forces that act on it, and in its speed. * If such a change causes further changes … Wikipedia
Lyapunov stability — In mathematics, the notion of Lyapunov stability occurs in the study of dynamical systems. In simple terms, if all solutions of the dynamical system that start out near an equilibrium point x e stay near x e forever, then x e is Lyapunov stable.… … Wikipedia
Relaxed stability — In aviation, relaxed stability is the tendency of an aircraft to change its attitude and angle of bank on its own accord. An aircraft with relaxed stability will oscillate in simple harmonic motion around a particular attitude at an increasing… … Wikipedia
positive static stability — The tendency of an aircraft to return to its original flight attitude after being disturbed by an external force. An aircraft is positively stable if it returns to level flight after it has been disturbed by, for instance, a gust … Aviation dictionary
