How do you calculate the Mass and Balance of the Seneca V?

• A. Using fuel charts
• B. Using performance graphs supplied in the POH
• C. Using crew weight
• D. Using maintenance logs

Answer: (B)

Mass and balance is all about how weight is distributed along the aircraft. To calculate it, you use the load data provided in the aircraft’s POH. For the Seneca V, the POH includes graphs that relate the gross weight to the ship’s moment or CG position, along with the corresponding allowable CG envelope. You determine the total weight by adding all loads (pilot and passenger weights, baggage, and fuel), then find the total moment by multiplying each load by its arm. The CG is the total moment divided by total weight. The graphs in the POH let you read the CG directly for a given gross weight or verify the CG lies within the permitted range for that weight. This ensures you’re using aircraft-specific data and staying within the allowable limits. Other options don’t fit because fuel charts alone don’t provide a full weight-and-balance picture, crew weight alone omits other loads, and maintenance logs don’t reflect current distribution of loads.
