What does the AUTO position do for the fuel transfer pump?

• A. Automatic operation
• B. Manual ON operation
• C. Off
• D. Reset

Answer: (A)

AUTO means the fuel transfer pump is controlled by the system and runs only as needed. The transfer pump moves fuel from the wing tanks to the engine feed to prevent fuel starvation and to help balance fuel between tanks. When in AUTO, the pump starts automatically if the engine-driven pumps can’t maintain adequate fuel pressure or if there’s a fuel imbalance, and it stops once pressures and balance are restored. This provides reliable fuel delivery with minimal pilot intervention, unlike the constant-on or off states.
