What factor affects the location of the center of gravity?

• A. The distribution of aircraft weight
• B. The color of the fuselage
• C. The altitude
• D. The battery type

Answer: (A)

The location of the center of gravity is determined by how the aircraft’s weight is distributed along its length. It’s essentially the balance point: if you shift weight toward the nose, the CG moves forward; if you shift it toward the tail, the CG moves aft. This is why the distribution of weight is the key factor—the CG is the weighted average position of all masses on the aircraft. Cosmetic or external factors don’t change where the mass is located. For example, color adds no weight distribution. Altitude affects performance and aerodynamics, not the geometric balance point. Battery type might change total weight or where the weight sits if the battery is placed differently, but the fundamental influence on CG comes from how mass is arranged along the aircraft. In practice, engineers and pilots manage CG by planning payload and component placement so the balance stays within the specified limits, ensuring stable and controllable flight.
