To perform a Piper Arrow IV weight and balance calculation, gather data on the aircraft’s empty weight, fuel load, passenger weights and seating locations, baggage weight and location, and any additional equipment. Calculate the total weight and moment for each item, then find the center of gravity (CG) by dividing the total moment by the total weight. Ensure the CG falls within the specified limits for safe flight.
