An airplane with the CG rear of the aft CG limit could potentially lead to what issue?

When an airplane has its center of gravity (CG) positioned aft of the aft CG limit, it can significantly affect the aircraft's handling characteristics and stability. Specifically, an excessive aft CG can result in a reduced ability to recover from unusual flight attitudes or adverse flight conditions. This configuration can make the airplane less stable, particularly in pitch, leading to a precarious flying condition where the aircraft could inadvertently become uncontrollable.

In this situation, the likelihood of inadvertent overstress increases because the pilot may have difficulty managing the aircraft's response correctly, especially during maneuvers or when encountering turbulence. The aircraft may be more prone to excessive rolling or pitching tendencies, which could push it beyond structural limits, hence increasing the risk of overstressing the airframe.

Understanding the implications of CG location is crucial for pilots, as it directly affects both the performance and safety of the flight. Maintaining the CG within specified limits is essential for ensuring the aircraft remains stable and controllable throughout all phases of the flight.
