What is the consequence of uneven weight distribution in an aircraft?

Uneven weight distribution in an aircraft has significant implications, especially during flight maneuvers. When weight is not evenly distributed, it causes the aircraft to behave unpredictably, particularly in terms of yawing motion. Adverse yaw occurs when the plane rolls to one side; as it does so, the wing on the side that is descending creates more lift but also more drag. This results in the aircraft yawing away from the intended turn direction rather than smoothly pivoting in the direction of the roll.

This effect can compromise both control and stability, particularly in turns. Therefore, the correct choice highlights how uneven weight can negatively impact the aircraft's handling characteristics, leading to adverse yaw, which is a critical factor for pilots to consider when managing aircraft performance and safety.

In contrast, while balanced weight distribution is essential for stability during turns, uneven distribution can lead to difficulties rather than aiding stability. Enhanced lift and reduced drag are outcomes typically associated with well-managed weight and center of gravity, not with uneven distribution.
