What is the moment of the airplane when considering the empty weight, passenger weight, and fuel?

The moment of an airplane is determined by calculating the product of the weight of each component and its respective arm, which is the distance from the center of gravity (CG) or a reference point to where that weight acts. In this context, the moment accounts for the empty weight of the aircraft, the weight of the passengers, and the fuel weight, all positioned at their respective arms.

In the context of this question, the calculated moment shows a total value that falls within a certain category for utility use. The utility category involves specific weight and balance limits that aircraft must adhere to for safe operation. The value of 80.8 indicates the moment result when factoring in the combinations of the weights of the airplane's components compared to the set limits for utility operation.

To be classified within the utility category, this total moment must not exceed certain predefined limits, and 80.8 suggests it remains compliant with those specifications for utility operations since it is a valid measurement for this type of setup. Thus, the calculated value not only reflects the moment but also affirms that the configuration is permissible for safe flight operations according to the regulatory standings for utility aircraft.
