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

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

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

The pitching moment coefficient is important in the study of the longitudinal static stability of aircraft and missiles.

The aerodynamic center plays an important role in analysis of the longitudinal static stability of aircraft and other flying vehicles.

This is longitudinal static stability.

Similarly, if the center of gravity is moved aft, the longitudinal static stability of the aircraft decreases.

We may analyse the longitudinal static stability by considering the aircraft in equilibrium under wing lift, tail force, and weight.

For an aircraft to return towards its trimmed attitude, without input from a pilot or autopilot, it must have positive longitudinal static stability.

This expression is dominated by , which defines the longitudinal static stability of the aircraft, it must be negative for stability.

Dunne successfully employed severely swept wings in his tailless aircraft as a means of creating positive longitudinal static stability.

Longitudinal static stability is the stability of an aircraft in the longitudinal, or pitching, plane under steady-flight conditions.

A tailless aircraft with a straight wing can be designed to have positive longitudinal static stability if the wing has reflex camber.

Canard foreplanes, being placed ahead of the center of gravity, act to reduce Longitudinal static stability (stability in pitch).

The longitudinal static stability of an aircraft is significantly influenced by the position of the center of gravity of the aircraft.

He authored An Introduction to the Longitudinal Static Stability of Low-Speed Aircraft in 1966.

A mathematical analysis of the longitudinal static stability of a complete aircraft (including horizontal stabilizer) yields the position of center of gravity at which stability is neutral.

This direction of movement of the center of pressure on a conventionally cambered airfoil is de-stabilising, necessitating a horizontal stabiliser to provide the aircraft with longitudinal static stability.

The way the center of pressure moves as lift coefficient changes makes it difficult to use the center of pressure in the mathematical analysis of longitudinal static stability of an aircraft.

In previous models, when operating at sustained high angles of attack, fuel migration would cause additional shifts in CG with the result that the aircraft had slightly negative longitudinal static stability.

For a tailless aircraft , 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.

They carried out some flight tests in a DC-3 with its centre of gravity 4.7% of MAC behind the rear limit and found there was a loss of longitudinal static stability that made it difficult to trim the aircraft for a constant airspeed but the low-speed flight handling qualities had not deteriorated seriously.
