When calculating CG for a loaded aircraft, which weights must be included?

The total weight of the aircraft, passengers, and cargo must be included when calculating the Center of Gravity (CG) for a loaded aircraft. This is crucial because the CG is influenced not just by the airframe itself but also significantly by the weight and distribution of all loads, including the passengers and cargo. An accurate CG calculation ensures that the aircraft maintains proper balance and stability during flight, which is vital for safe operation.

Including all of these weights helps in determining the overall center of gravity location, which affects flight dynamics such as control and handling characteristics. Ignoring any of these factors could result in a miscalculation, leading to potential safety issues during operation.

In contrast, options that suggest excluding certain elements like fuel, cargo, or passengers do not provide a complete picture of the aircraft's loaded state. For a safe and effective flight operation, it's essential to account for the total weight, including every component that contributes to the aircraft's overall load.
