What are the consequences of a CG that is too far forward?

When the center of gravity (CG) of an aircraft is positioned too far forward, it can significantly impact the aircraft's handling characteristics. With a forward CG, the aircraft may experience reduced control effectiveness; this is due to the fact that the tail surfaces must work harder to counteract the nose-heavy condition. This results in a greater pitch-down moment, which can make it more challenging for the pilot to maintain level flight and control the aircraft effectively.

Additionally, a forward CG can lead to difficulties in maneuverability. The aircraft may require more aileron input to induce roll, making it less responsive to pilot commands, especially at low speeds. Furthermore, if the CG is excessively forward, it can impact the aircraft's ability to achieve adequate climb performance due to increased drag on the tail surfaces.

In contrast, options focused on increased lift, speed, or fuel consumption do not accurately reflect the aerodynamic realities associated with an excessively forward CG, which compromises control and handling rather than improving efficiency or performance.
