Does anyone have any sources that can tell the the number of fueling nozzles and the fueling rate for a Cessna Citation X+ or a Cessna Citation X?


1 Answer 1


Basically fuelling time depends on how fast the hydrant or fuel truck can deliver fuel.

This comes from SmartCockpit:

The Citation X fuel system is comprised of the storage, distribution, refueling/defueling,and indicating systems. The storage system is made up of a set of integral tanks in each wing, and a center wing tank which includes a forward fairing fuel tank. Each wing tank has a hopper tank which is integral to it. The two wing tanks incorporate check valves and baffles allowing each wing tank complex to function as a single tank. Other integral components of the storage system are the gravity fuel fillers, drain valves, flapper check valves, vent system components,
positive/negative pressure relief valves and all of the associated system plumbing. Transfer capability is incorporated enabling all usable fuel to be available to either engine.Each wing tank holds a total of 521 gallons (3518 Lbs.) of fuel, which includes the hopper tank. The center wing tank holds 888 gallons (5594 Lbs.), 207 (1397 Lbs.) of which are contained in the forward fairing tank.
Total fuel capacity of the airplane fuel system is 1927 gallons; at 6.75 pounds per gallon the available fuel weight is 13,031 pounds.


The single-point refueling system is provided to enable the airplane to be refueled or de-fueled more safely and conveniently by connecting to one port, which is not open to the atmosphere. Advantages of a single-point refueling
and defueling include minimized refuel/defuel time, reduced possibilities of fuel contamination, reduced static
electricity hazard, less airplane skin damage, and there is no personnel contact with the fuel.The refueling/defueling system is independent of the airplane system. It is designed for refueling with a truck or refueling hydrant (pit) having single point provisions. The major components of the system include the refueling/defueling adapter (receptacle), the precheck control panel, refuel shutoff valves, the pilot (precheck) valves, defuel valves, a sequencing valve, manual
defuel select shutoff valves, internal drain valves and associated system plumbing.Single-point refueling is accomplished by connecting the refueling truck or refueling pit equipment to the airplane at the single-point refuel/defuel adapter on the right side of the fuselage just forward of the wing leading edge.

    $\begingroup$ Just as a really general idea, however, single point fueling trucks fairly routinely have flow rates in the vicinity of 200-250 US gallons per minute. $\endgroup$ Commented Oct 8, 2020 at 6:41
