What is a potential issue with an airplane loaded with the Center of Gravity aft of the rear CG limit?

Loading an airplane with the center of gravity (CG) aft of the rear CG limit can lead to serious handling issues, primarily pitch instability. When the CG is too far back, the aircraft can become difficult to control, especially during maneuvers that require a change in pitch, like takeoff and landing.

This instability occurs because the natural aerodynamic forces acting on the aircraft can no longer produce enough restoring moment to counteract small disturbances in pitch. As a result, the aircraft may respond sluggishly or erratically to inputs from the pilot, making it challenging to maintain a desired flight path or to recover from pitch changes.

Understanding this concept is crucial in aircraft operations, as knowing the proper loading and CG limits ensures safety and performance are maintained throughout the flight.
