How do the FUEL TRANSFER pumps operate with the switches in ON?

• A. They will run continuously until manually shut off
• B. They only check pump operation and do not provide auto shutoff
• C. They automatically shut off when pressure is adequate
• D. They function normally regardless of system status

Answer: (B)

The correct answer states that the fuel transfer pumps only check pump operation and do not provide auto shutoff. This means that when the switches for the fuel transfer pumps are turned ON, the pumps initiate a self-check process to ensure they are functioning properly, but they will not automatically turn off once they have achieved adequate pressure. In most aircraft systems, fuel transfer pumps are designed to provide operational redundancy and security. They constantly check their operation to confirm that they are responsive and functioning as expected, but the absence of an automatic shutoff feature means that the pilot or crew must monitor the system manually. Understanding this mechanism is crucial for safe operation, as it informs the crew that they should remain vigilant regarding pump activity to prevent potential issues such as fuel overflow or system malfunctions.
