How does an aft centre of gravity typically affect stall characteristics?

An aft center of gravity configuration can significantly increase the risk of an aircraft entering a stall condition. When the center of gravity is positioned towards the aft, it alters the balance and aerodynamic characteristics of the aircraft. Specifically, this can decrease the amount of effective control authority and stability, especially in pitch.

With the center of gravity further back, the aircraft may not have adequate nose-down authority to recover from a stall. This shift leads to a greater likelihood that a stall will occur at a higher airspeed, which can be particularly hazardous during critical phases of flight such as takeoff and landing. Additionally, the aircraft may exhibit a tendency to pitch up more easily, which increases the chances of exceeding the critical angle of attack, where stall conditions begin.

Understanding this relationship is crucial for pilots, as maintaining an appropriate center of gravity within the recommended limits contributes to safer flight operations and minimizes the risks associated with stall situations.
