The fuel system contains how many AC-powered fuel transfer pumps?

Explanation:
Redundancy and reliable fuel distribution across all tanks are achieved by having multiple independent pumps. Ten AC-powered fuel transfer pumps provide enough parallel paths to move fuel between tanks and to the engines under all operating conditions. This setup ensures engine feed and center-of-gravity control remain achievable even if several pumps are out of service, maintaining flight safety and performance. Fewer pumps would reduce transfer capability and fault tolerance, while more pumps would add unnecessary weight and complexity, so ten pumps reflect the designed balance for this system.
