What is the typical weight of fuel that is unusable under normal conditions in the MQ-9?

The typical weight of unusable fuel in the MQ-9 is indeed around 60 pounds. This figure represents the amount of fuel that cannot be drawn from the fuel tanks during normal flight operations due to the design and operational limitations of the aircraft's fuel system.

In unmanned systems like the MQ-9, having a precise understanding of available versus unusable fuel is crucial for flight planning and mission execution. Knowing that 60 pounds is unusable allows operators to account more accurately for the aircraft's range, endurance, and overall performance. Understanding this concept is essential for effective mission planning and ensuring safe operations, especially in a system that requires careful management of resources like fuel.

The other figures do not align with the established specifications for the MQ-9, making them less relevant in this context.
