Which statement concerning an electronic capacitance-type fuel quantity indicating system is true?

An electronic capacitance-type fuel quantity indicating system is designed to measure fuel levels without employing moving parts inside the fuel tank, which contributes to its reliability and reduced maintenance requirements. This system operates based on the principle of capacitance, where the amount of fuel in the tank changes the capacitance between electrodes or plates. Because there are no mechanical components subject to wear or mechanical failure, this technology enhances the accuracy and longevity of the fuel measurement system.

The other statements refer to characteristics that do not apply to capacitance-type systems. For instance, they imply the use of mechanical gauges or hydraulic pressures, which are not needed for capacitance measurements. Additionally, a capacitance-type system can continuously monitor fuel levels, not just at a single point in time. This capacity allows for real-time monitoring and more effective fuel management in aircraft systems.
