What is the typical location of the CG of the airfoil relative to the aircraft CG?

The center of gravity (CG) of an airfoil is typically located aft of the aircraft's overall center of gravity. This positioning is crucial for maintaining the aircraft's stability and control. When the airfoil's CG is behind the aircraft's CG, it promotes a nose-down moment, which assists in maintaining stability during flight.

If the airfoil's CG were located forward of the aircraft's CG, it could lead to a nose-up attitude that might compromise the aircraft's stability and control. Having the airfoil's CG aft helps achieve a balance that enables proper lift generation and enhances the overall aerodynamic performance of the aircraft.

In normal aircraft design, ensuring that the airfoil CG is appropriately placed allows for optimal stability during various phases of flight, as the forces acting upon the aircraft operate within predictable parameters. This design consideration is fundamental for safe and efficient aircraft operation.
