What is the primary purpose of weight and balance calculations?

• A. Ensure safe loading and stability
• B. Optimize fuel efficiency
• C. Plan crew shifts
• D. Determine insurance requirements

Answer: (A)

Weight and balance calculations establish the total weight and how it’s distributed in the aircraft to keep the center of gravity within the approved envelope. The primary aim is safe loading and stability: keeping the CG within forward and aft limits ensures the aircraft remains controllable and predictable throughout takeoff, flight, and landing. If the CG is too forward, elevator authority can be reduced and pitch control becomes sluggish; if it’s too far aft, longitudinal stability can be compromised, making the airplane harder to control and increasing tendency toward unstable handling. The calculations also verify that loads, fuel, and payload stay within structural and weight limits, preventing overstress or performance issues. While weight and balance affect overall efficiency, the central purpose is safety and reliable handling, not fuel economy, crew scheduling, or insurance requirements.
