What configuration at the center of gravity results in a stable aircraft?

• A. All weight in the wings
• B. All weight at the tail
• C. All weight at the center
• D. All weight at the nose

Answer: (C)

A stable aircraft configuration is achieved when the center of gravity (CG) is positioned in such a way that any disturbance from its flight path will be corrected naturally. When the weight is centered properly, as indicated in the selected answer, the aircraft is able to maintain a balanced state. This is because the lift generated by the wings is directly aligned with the aircraft's center of gravity, allowing for efficient control and stability in flight. In contrast, when weight is concentrated in the wings, tail, or nose, it can lead to an imbalance. For instance, having all the weight at the wings might cause the aircraft to pitch up or down excessively, while weight concentrated at the tail could lead to a tail-heavy condition, making the aircraft challenging to control. Similarly, a nose-heavy configuration can result in excessive forward pitching and potential loss of control. Thus, a configuration where all weight is centralized helps ensure that any deviations from level flight can be corrected through aerodynamic forces, leading to a more stable and controlled flying experience.
