Which of the following describes the function of center of gravity in an aircraft?

The function of the center of gravity (CG) in an aircraft is crucial to its aerodynamic balance. The center of gravity is the point at which the aircraft's weight is evenly distributed. When the CG is properly positioned, it allows the aircraft to fly smoothly and maintain stability during flight. An aircraft with a well-balanced CG can achieve a more efficient aerodynamic performance, which is essential for safety and maneuverability.

If the center of gravity is too far forward or too far aft, it can lead to difficulties in controlling the aircraft. A forward CG can result in a nose-heavy situation, making it harder to pull up, while an aft CG can create a tail-heavy condition that can lead to stalling. Therefore, understanding the CG’s position and its effect on aerodynamic balance is vital for pilots in maintaining control during flight.

Other choices may touch on various aspects of flight performance, but they do not directly relate to the fundamental role of the center of gravity in ensuring that an aircraft remains balanced during flight.
