How is the center of gravity of an aircraft determined?

• A. By using the total weight only
• B. By dividing total moment by total weight
• C. By measuring wing span
• D. By calculating thrust to weight ratio

Answer: (B)

The center of gravity (CG) of an aircraft is determined by dividing the total moment by the total weight. The total moment is calculated from the weights of all components of the aircraft (including passengers, cargo, fuel, etc.) multiplied by their respective distances from a reference point, typically the nose of the aircraft. This process effectively gives a weighted average of the locations of the weights concerning the aircraft's reference point. To find the center of gravity, this total moment is then divided by the total weight of the aircraft. This formula is essential for achieving proper weight distribution, which affects the aircraft's balance, stability, and controllability during flight. Understanding the CG is crucial for flight safety, as improper balance can lead to difficulty in controlling the aircraft. Thus, using the relationship between total moment and total weight provides the most accurate method to locate the CG and ensures that the aircraft operates within its design parameters.
