How many fuel probes are positioned in the fuselage tanks?

The correct answer indicates that there are four fuel probes positioned in the fuselage tanks. These probes are essential for accurately measuring the fuel levels within the tanks, ensuring that pilots have reliable information for fuel management and planning during flight operations. The multiple probes provide redundancy and enhance the accuracy of readings, which is crucial in maintaining safety and efficiency in fuel usage.

Having four fuel probes allows for a more precise assessment of fuel levels, as they can collectively account for variations in tank shape and fuel movement during maneuvers. This design can help identify potential issues, such as fuel imbalance or leaks, by providing comprehensive data from multiple points within the tanks.

In contrast, other options suggesting fewer or more probes do not align with the standard design and operational requirements of the aircraft in question. Understanding the specific configuration of fuel probes is vital for pilots and maintenance crews for effective fuel management and operational safety.
