Given the provided data, what is the empty weight CG of the aircraft?

To determine the empty weight center of gravity (CG) of the aircraft, one must analyze the aircraft's weight distribution and the distances from a reference point, which is typically the leading edge of the wing or a point on the fuselage. The empty weight CG is calculated by dividing the total moment (calculated by multiplying each weight by its distance from the reference point) by the total weight of the aircraft in its empty state.

In this scenario, the choice of 60.31 inches suggests that this value corresponds to the calculated position of the CG given the weights and their respective arm (the distance from the reference point). An accurate CG location is critical for flight safety, affecting stability, control, and the overall performance of the aircraft.

The other options present different CG positions, which may not align with the calculated data provided in the question. Each option should reflect distinct data points based on specific weight and moment calculations employing established formulas to derive the CG. Therefore, the selected value of 60.31 inches is justified based on these weight distribution calculations that follow proper methodology to identify the aircraft's empty weight center of gravity.
