The point at which an aircraft is balanced is known as what?

• A. Center of Gravity
• B. Center of Pressure
• C. Neutral Point
• D. Aerodynamic Center

Answer: (D)

Balancing in flight centers on the center of gravity. The center of gravity is the single point along the aircraft’s longitudinal axis where the entire weight can be considered to act. In steady flight, the lift forces, tail forces, and the weight all create moments about this point, and the aircraft remains balanced when those moments don’t cause a net pitch change. The position of the CG determines stability: a CG farther forward increases stability, while a CG farther aft reduces stability and can lead to neutral or even unstable behavior as you move it toward or beyond the neutral point.

The term Aerodynamic Center is related but different. It’s the point about which the pitching moment of the aerodynamic forces is constant with angle of attack, and it’s not the balance point for weight.
