Which statement correctly reflects the function of the center of lift in relation to the center of gravity (CG)?

The correct answer highlights that the center of lift should be behind the center of gravity for stability. In an aircraft, the center of gravity is the point where the mass of the aircraft is concentrated, while the center of lift is the average location of the lift force acting on the wings.

When the center of lift is located behind the center of gravity, it creates a natural tendency for the aircraft to right itself during minor disturbances in attitude. This configuration generates a stabilizing moment that returns the aircraft to level flight if it pitches up or down. This principle is critical for a stable flight, as it helps maintain control and keeps the aircraft from becoming uncontrollable during various maneuvers or turbulent conditions.

While having the center of lift ahead of the center of gravity may lead to easy initial flight control, it often results in an unstable aircraft that is prone to pitching uncontrollable. The function of the center of lift, therefore, is essential to ensuring that the aircraft behaves predictably and remains manageable during flight operations.
