What is the correct term for the point where the aircraft's weight is balanced in flight?

The center of gravity is the correct term for the point where the aircraft's weight is balanced in flight. It represents the average location of the weight of the aircraft and is critical to maintaining stability and control during flight. When the center of gravity is correctly positioned, it ensures that the aircraft is balanced around its axes, which affects the aircraft's performance characteristics, including maneuverability and control effectiveness.

Understanding the center of gravity is fundamental for pilots and engineers, as it impacts aircraft handling. If the center of gravity is too far forward or aft, it can lead to difficulties in controlling the aircraft, potentially resulting in unsafe situations.

The other terms mentioned do not accurately describe the balance point of the aircraft's weight. The aerodynamic center relates more to the lift distribution and stability of an airfoil rather than the weight of the aircraft. The center of pressure pertains to the point where the total aerodynamic lift force acts on the wing, which can change with the angle of attack. The weight distribution center is not a commonly used term in aviation and does not convey the concept of balance in the same way that the center of gravity does.
