These must generate large control forces, as their distance from the aerodynamic center is small and the moments less.

Some other method must be used to move the aerodynamic center backward and make the aircraft stable.

For this reason, it is much simpler to use the aerodynamic center when carrying out a mathematical analysis.

The aerodynamic center is the conceptual starting point for longitudinal stability.

The concept of the aerodynamic center (AC) is important in aerodynamics.

The actual aerodynamic center of the Columbia was upstream from the calculated value due to real-gas effects.

As the Concorde reached supersonic speeds, its aerodynamic center of lift shifted backward.

The aerodynamic center, AC, is at the quarter-chord point.

The aerodynamic center occupies a fixed location on an airfoil, typically close to the quarter-chord point.

Consequently, the aerodynamic center moves upstream thus causing aerodynamic instability.

Pitching moment coefficient is fundamental to the definition of aerodynamic center of an airfoil.

However, unexpected movement of the car's aerodynamic centre of pressure made its handling unpredictable and the new engine was unreliable.

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

At supersonic airspeed, a negatively stable aircraft can exhibit positive static stability due to aerodynamic center migration.

The pressure distribution over the entire wing can be reduced to a single lift force on and a moment around the aerodynamic center of the MAC.

The configuration, combined with a center of gravity well aft of the aerodynamic center, made the craft inherently unstable.

Due to the high forces involved in tail balancing loads, stabilators are designed to pivot about their aerodynamic center (near the tail's mean quarter-chord).

For non-symmetric (cambered) airfoils the quarter-chord is only an approximation for the aerodynamic center.

The aerodynamic center of an airfoil is usually close to 25% of the chord behind the leading edge of the airfoil.

Providing the center of gravity of an aircraft lies forward of the aerodynamic center the aircraft will have positive longitudinal stability.

The aerodynamic center, which is the chord-wise length about which the pitching moment is independent of the lift coefficient and the angle of attack.

For symmetric airfoils in subsonic flight the aerodynamic center is located approximately 25% of the chord from the leading edge of the airfoil.

Longitudinal stability in tailless aircraft is achieved by designing the aircraft so that its aerodynamic center is behind the center of gravity.

Because of this the aerodynamic center of an ordinary wing would lie ahead of the aircraft's center of gravity, creating instability in pitch.

Such an aerofoil is useful in certain situations, such as with tailless aircraft, because the moment about the aerodynamic center of the aerofoil can be 0.
