Maximum useful load?

Maximum useful load?

• A. 600 lbs
• B. 580 lbs
• C. 563 lbs
• D. 540 lbs

Answer: (C)

The maximum useful load is the weight you can carry beyond the airplane’s empty weight up to its certified maximum gross weight. In practice, you determine it by subtracting the basic empty weight from the maximum gross weight. That difference represents the combined weight of crew, passengers, baggage, and usable fuel that can be on board. In this problem, the figures given (maximum gross weight and empty weight) yield a difference of 563 pounds. That means you can load up to 563 pounds of useful load without exceeding the aircraft’s weight limit. Loading more would push the aircraft beyond its certified gross weight. Keep in mind that, in addition to weight, the center of gravity must also remain within the allowable envelope; even if you’re within the useful-load limit, an improper distribution could violate CG limits.
