Which item is a component of the fuel quantity indication system that sends fuel data from the tank to the cockpit?

• A. Indicator
• B. Transmitter
• C. Monitoring
• D. Sensor

Answer: (B)

The key idea is that fuel data must be sent from the tank to the cockpit, and this relies on a device that transmits that information. In a fuel quantity indication system, sensors in the tank (such as float, capacitance, or ultrasonic sensors) actually measure how much fuel is present. The transmitter then converts that measurement into a signal and sends it to the cockpit where the fuel quantity indicator displays it. The transmitter is the part that bridges the in-tank measurement and the cockpit display. The indicator is just the display in the cockpit; it shows the value but doesn’t carry the signal from the tank. Monitoring is a general term for observing the data, not the device that transmits it. A sensor is the measuring element in the tank, but by itself it doesn’t push the data to the cockpit—the transmission step is needed to complete the data path.
