Which system does Whitewind Company use to compute weight and balance?

• A. Auto Nav
• B. Weight Balance Pro
• C. Ultra Nav
• D. SkyCalc

Answer: (C)

Weight and balance calculations determine where the aircraft’s center of gravity lies and ensure the load stays within safe limits for the planned weight. A system designed for this task takes input data such as basic empty weight and moment, crew and passenger weight, baggage, fuel, and expected fuel burn, then computes total weight and total moment. It then derives the center of gravity by dividing the total moment by the total weight and checks that the CG falls inside the aircraft’s forward and aft limits for the expected weight category (zero fuel weight, ramp, takeoff). It can also generate a load sheet and flag any loading that would push the aircraft out of limits.

In this scenario, the system Whitewind Company uses to compute weight and balance is Ultra Nav, because it’s described as the tool handling weight and balance calculations. The other names imply navigation or generic calculation tools rather than a dedicated weight-and-balance solution, so they wouldn’t be the logical choice for performing precise W&B computations.
