What is the role of gauges in single point refueling?

• A. They permit fueling to a predetermined point
• B. They measure the fuel color
• C. They control the pump speed
• D. They log fuel temperature

Answer: (A)

In single point refueling, gauges provide a measurement of how much fuel has been pumped, so fueling can be stopped at a pre-set quantity. The gauge signals when the target fuel load is reached, ensuring the aircraft is filled accurately and preventing overfill, which is crucial for weight, balance, and safety. Other aspects like color of fuel, pump speed, or temperature logging aren’t the purpose of these gauges; color isn't a metering cue, pump speed is controlled by the fueling system separately, and temperature is monitored by other sensors.
