What can cause the transfer pump automatic shut off?

• A. A low quantity condition in System 2 or 3
• B. Overpressure in System 2
• C. A low quantity condition in System 1 or 4
• D. Pressure between 3400 and 4000 in System 2 or 3

Answer: (A)

The automatic shut-off of the transfer pump is triggered when there is a low quantity condition in System 2 or 3. This mechanism is designed to prevent damage to the fuel transfer system and ensure operational safety. When the fuel levels drop below a certain threshold, the system's sensors detect this condition and prompt the pump to shut down to avoid running dry, which could lead to pump failure or reduced system efficiency. Ensuring adequate fuel quantities is critical for maintaining the performance and reliability of the aircraft's systems during operations, as it ensures that all planned transfers can be completed effectively without risking component damage.
