Abstract: An electronic fueling data acquisition and wireless communications delivery system. The unit is mounted on Aircraft Fueling Vehicles and Aircraft Fuel Servicing Hydrant Vehicles (Hydrant Vehicles) and is hardwired to an external pulse transmitter. The pulse transmitter transmits pulse signals proportional to the volume of fuel that is being pumped. A software configurable hardware filter attenuates the input signal which is then counted by a pulse accumulator. When fueling ceases, the application software can convert the pulse signal values to an equivalent volumetric total. The information can then be wirelessly communicated to other devices without the need for maintaining paper hard copies.

Abstract: A fueling agent operates a fueling agent client device for collecting and generating transaction data relating to a fueling transaction. The fueling agent client device transmits the transaction data to a fuel management server, for example, via a wireless communications link. The fuel management server stores the transaction data in a transaction record. The transaction data includes final fuel load data indicating an amount of fuel dispensed during the fueling transaction. Selected transaction data is retrieved from the transaction record and is delivered to a data communications system for transmission to a receiver. The receiver may be in the cockpit of an aircraft. An aircraft data communication system may be a digital data link system for transmitting data to and from the aircraft via VHF radio, such as ACARS. The fuel management server may communicate with an aircraft data communication system directly, or indirectly via an airline computer system.
