Definition#
Center of gravity (CG) is the point at which the total weight of the aircraft can be considered to act. Its longitudinal position relative to the wing's mean aerodynamic chord determines pitch stability and trim requirements.
Why It Matters Operationally#
A CG that is too far aft makes the aircraft unstable; too far forward requires excessive control force and increases stall speed. Proper loading and fuel management keep CG within limits.
