How much imbalance can automatic balancing handle by itself?

• A. 178 lbs
• B. 267 lbs
• C. 300 lbs
• D. 330 lbs

Answer: (B)

Automatic balancing has a finite capacity to correct weight differences on its own. On the PC-12 NGX, it can automatically compensate for an imbalance up to about 267 pounds. That means if the load creates a lateral or longitudinal offset no greater than 267 pounds, the system can rebalance by shifting fuel between tanks or adjusting ballast to keep the center of gravity within acceptable limits.

If the imbalance exceeds that amount, manual rebalancing is required—move passengers or cargo, or adjust fuel distribution—so the load falls within what the automatic system can handle. This limit is separate from the aircraft’s gross weight or CG envelope; it specifically defines how much imbalance the automatic balancing can correct without pilot action.
