A capacitance type fuel quantity indicating system measures fuel in?

A capacitance type fuel quantity indicating system measures fuel in pounds because it relies on the principle of capacitance, which varies with the amount of fuel present in the tank. This measurement is often calibrated to reflect the weight of the fuel, which is essential for various flight planning and operational considerations.

Fuel quantity in pounds is closely related to the aircraft's weight and balance, which are critical factors in aviation. By measuring fuel in pounds rather than volume (like gallons or liters), pilots and engineers can more easily integrate this information into calculations that influence the aircraft's performance and safety. Additionally, pounds as a measure aligns with other weight-based metrics in aviation, providing a more straightforward understanding of how much fuel is present and its implications for the aircraft's total weight.
