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.
