What benefit does an aft CG position provide during flight?

An aft center of gravity (CG) position improves the aircraft's aerodynamic efficiency, allowing for a reduction in stalling speed. When the CG is positioned toward the rear of the aircraft, it enhances the stability and maneuverability, which allows the aircraft to maintain controlled flight at lower speeds and enables flying at higher altitudes. This is particularly beneficial during cruise and in maneuvers where the aircraft might otherwise stall at higher speeds.

The reduction in stalling speed means the aircraft can operate efficiently within a broader range of flight parameters, allowing pilots to utilize higher altitudes safely. Higher altitudes typically provide better fuel efficiency and longer range, as thinner air results in less drag on the aircraft.
