Which action is primarily used to prevent load and balance changes during boarding?

• A. Keep passengers in allocated seats
• B. Move passengers to balance
• C. Have passengers stand during takeoff
• D. Distribute seats randomly

Answer: (A)

Maintaining a stable weight distribution as people board is essential for safe load and balance. Keeping passengers in their allocated seats ensures the calculated center of gravity (CG) remains as planned on the load sheet. When people move around or stand, the CG shifts, which can affect aircraft controllability and performance and may require last‑minute rebalancing. Allowing seats to be chosen randomly or having passengers stand would introduce unpredictable shifts in weight, while actively moving passengers to rebalance during boarding adds unnecessary changes and complexity. Therefore, the most effective way to prevent load and balance changes during boarding is to keep passengers in their allocated seats.
