What is the total usable fuel for the PC-12 NGX?

• A. 2,650 lbs
• B. 2,703 lbs
• C. 2,800 lbs
• D. 2,750 lbs

Answer: (B)

Understanding usable fuel is key for accurate flight planning. Usable fuel is the amount of fuel that can actually be drawn from the tanks and burned in flight; it excludes a small amount that remains unusable due to tank geometry and fuel line design.

For the PC-12 NGX, the published total usable fuel is 2,703 pounds. This is the figure you’d use for endurance and range calculations, including reserves, because it represents what you can reliably burn in flight. The other numbers don’t match the official specification for usable fuel. They might reflect total fuel capacity or other fuel quantities, but they aren’t the usable-fuel figure you’d use for planning. Roughly, this usable amount corresponds to about 400 gallons of Jet-A, depending on fuel density.
