What could excessive weight in the aft CG scenario lead to?

In an aircraft, the center of gravity (CG) is a critical factor that significantly impacts flight performance and safety. When the CG is positioned excessively toward the aft, or rear, part of the aircraft, it alters the dynamics of flight.

Having an aft CG scenario can lead to reduced stability. In such a configuration, the aircraft may become easier to manipulate in pitch, but this can come at the cost of increased sensitivity. As a result, the aircraft can encounter a higher likelihood of stalls, particularly when the pilot attempts to maneuver or turn. Stalls occur when the wings are unable to generate sufficient lift, typically due to a high angle of attack. This situation can quickly lead to loss of control if not managed properly.

In contrast, a forward CG tends to provide better stability, making the aircraft easier to handle, particularly at lower speeds. Hence, an aft CG configuration compromises these qualities, increasing the risk during flight operations. The other options do not accurately reflect the implications of an aft CG; improvements in stability, fuel consumption, or the idea that there are no negative effects do not align with the well-documented risks associated with excessive weight in the aft CG.
