How many fuel probes does the fuel quantity indicating system utilize?

The fuel quantity indicating system typically utilizes a specific configuration of fuel probes to accurately measure and report the amount of fuel in the tanks. The correct answer indicates that the system employs a total of seven probes, divided into three for the left tank, one for the right tank, and three for the center tank.

This setup is crucial for providing accurate and reliable readings of the fuel levels, which is essential for flight safety and operational efficiency. Each probe is designed to measure fuel quantity at different points in the tanks to account for variations in fuel distribution, ensuring that pilots have a precise understanding of how much fuel is available during flight operations.

Understanding the configuration and number of probes in the fuel quantity indicating system is important as it can affect fuel management and ensure that aircraft operate within safe limits.
