Abstract:
1. A fueling control system for providing fuel from a vehicle to an aircraft comprising: a pressure transducer for sensing back pressure in a fluid path to a fuel tank of an aircraft, and a digital controller coupled to the pressure transducer for receiving the back pressure in the fluid path and controlling fuel flow in the fluid path to the aircraft, wherein the digital controller is coupled to a pump in the vehicle for controlling speed of the pump for pumping the fuel in the fluid path, and the digital controller includes at least two relationships between the back pressure in the fluid path and the flow rate of the fuel in the fluid path stored in a memory device; wherein one relationship sets a first speed of the pump to control pumping of the fuel at a first rate, and a second relationship sets a second speed of the pump to control pumping of the fuel at a second rate; and the first and second rates are dependent on the sensed first and second back pressures in the fluid path, respectively.
