Approximately how much fuel is considered unusable in the MQ-9?

The amount of fuel considered unusable in the MQ-9 is typically around 1-2%, which is approximately 60 pounds. In aviation, unusable fuel refers to the fuel that cannot be drawn from the tanks due to design limitations, resulting in a portion of the fuel being left unutilized. This is crucial for flight planning and operational readiness, as it ensures that the aircraft has a reliable estimate of the fuel it can actually use for missions.

Statistically, understanding this range of unusable fuel helps pilots and operators manage their fuel loads effectively, ensuring safe and efficient flight operations. It aids in calculating the total range, endurance, and payload capacity of the aircraft, facilitating better mission planning and overall operational efficiency.
