Multiple Choice

Using the primary refueling method, how many pounds of usable JP-8 fuel are provided?

This question tests understanding of the fixed amount of usable JP-8 fuel allocated by the primary refueling method. The primary method is designed to deliver a defined quantity of usable fuel, accounting for unavoidable losses in lines and fittings, so crews have a predictable planning figure that keeps weight within limits while providing enough for the mission and required reserves. JP-8 weighs about 6.8 pounds per gallon, so 1100 pounds of usable fuel is roughly 160 gallons. This amount gives a practical balance: enough fuel for typical missions and needed reserves without pushing the aircraft over weight limits. A thousand pounds would fall short of the standard usable quantity and could reduce reserves; twelve hundred pounds would exceed the usual allocation; and two thousand one hundred pounds is far beyond what this method provides. Therefore, 1100 pounds is the correct usable fuel amount provided by the primary refueling method.
