What happens to pitch control as the centre of gravity shifts forward?

When the center of gravity shifts forward in an aircraft, it leads to an increase in the nose-down moment due to the weight being positioned further away from the aerodynamic center of the wing. Consequently, the aircraft experiences a change in its pitch stability and control characteristics.

As the center of gravity moves forward, the required control forces on the elevator to maintain a desired pitch attitude increase. This makes the elevator response more sensitive because even small inputs will produce larger changes in pitch angle. The pilot must also deal with overcoming the increased tendency of the aircraft to pitch down, which adds to the need for precise control inputs.

This increased sensitivity in pitch control can affect how the aircraft feels during flight, requiring the pilot to be more attentive and responsive to control inputs. In summary, the adjustment in pitch control sensitivity due to the forward shift of the center of gravity is a critical consideration for pilots in maintaining stable flight.
