[5] [4] The distance between the center of gravity and the neutral point is defined as "static margin". It is usually given as a percentage of the mean aerodynamic chord. [6]: 92 If the center of gravity is forward of the neutral point, the static margin is positive.
The stiffness does not only depend on the static stability term , it also contains a term which effectively determines the angle of attack due to the body rotation. The distance of the center of lift, including this term, ahead of the centre of gravity is called the maneuver margin. It must be negative for stability.
Static stability is the ability of a robot to remain upright when at rest, or under acceleration and deceleration Static stability may also refer to: In aircraft or missiles: Static margin — a concept used to characterize the static stability and controllability of aircraft and missiles.

The Static Margin can then be used to quantify the AC: = where: C n = yawing moment coefficient; C m = pitching moment coefficient; C l = rolling moment coefficient; C x = X-force ≈ Drag; C y = Y-force ≈ Side Force; C z = Z-force ≈ Lift; ref = reference point (about which moments were taken) c = reference length
