How many fuel probes are located in the wing tanks?

The correct answer is based on the design of the wing fuel system in many aircraft, where multiple fuel probes are strategically placed to provide accurate readings of the fuel levels within the tanks. In this case, having four fuel probes is typical for ensuring redundancy and accuracy in measuring the fuel quantity.

Each of the probes serves to measure the amount of fuel in different sections of the wing tank, thus allowing for a more precise understanding of fuel consumption and remaining fuel, enhancing operational safety. The presence of multiple probes also mitigates the risk of a single point of failure affecting fuel level reporting, which is critical for flight planning and in-flight management.

Understanding the configuration of fuel probes is essential for pilots and maintenance personnel, as it directly impacts fuel management strategies during flight.
