Patent ID: 8888046

Claim:
A computer-implemented fuel management method for monitoring and minimizing a fuel consumption of an aircraft, comprising: determining, on the basis of model assumptions, a theoretical value of a first quantity of fuel that is necessary for travelling along at least one sector of a flight route, the first quantity of fuel comprising one or more of a quantity of fuel required for taxiing of the aircraft, a quantity of fuel required for travelling along the at least one sector of the flight route of the aircraft, and a quantity of fuel required for contingency; determining a practical value of a second quantity of fuel that is necessary for travelling along a remaining flight distance of the at least one sector of the flight route, taking into account a plurality of actual measured values; comparing the theoretical value of the first quantity of fuel with the practical value of the second quantity of fuel; and providing at least one measure in order to save fuel during the flight when the practical value of the second quantity of fuel differs from the theoretical value of the first quantity of fuel by a predeterminable amount; wherein the at least one measure for saving fuel during the flight comprises reduction of the energy consumption of at least one on-board system; wherein the at least one measure is provided by a fuel management system.
