This makes the center of pressure unsuitable for use in analysis of longitudinal static stability.

As the center of gravity moves forward the longitudinal static stability of the aircraft increases.

Pitching moment due to incidence - the static stability term.

With the center of gravity forward of the neutral point, an aircraft has positive longitudinal static stability.

The first condition above is positive static stability.

The second condition above is negative static stability.

An other role of a longitudinal stabilizer is to provide longitudinal static stability.

However, positive static stability; the tendency to remain in its current attitude; opposes the pilot's efforts to maneuver.

An aircraft with negative static stability can therefore be made more maneuverable.

Yaw:A bullet's base has more mass than its nose - a shape lacking static stability.
