Abstract

A method of determining an overall fuel allocation and a method of loading fuel onto one or more aircraft according to the overall fuel allocation; and a fuel allocation determination system for missions performed by at least one aircraft, supplied with fuel from a fuel source including an amount of a first fuel and of a different second fuel. The method includes: determining one or more utility values for each mission of the plurality of missions, wherein the or each utility value for each mission is based on the same one or more of a predicted contrail outcome and a predicted local air quality outcome; determining an ordering of the missions of the plurality of missions based on the or each utility value of each mission; and determining the overall fuel allocation for the plurality of missions based on the ordering of the missions.

Dependent claims

A computer implemented method of determining an overall fuel allocation for a plurality of missions carried out by one or more aircraft, the plurality of missions being supplied with fuel from a fuel source, the fuel source comprising an amount of a first fuel and an amount of a second fuel, each mission of the plurality of missions being supplied with an amount of the first fuel and an amount of the second fuel, the overall fuel allocation indicating an amount of the first fuel and an amount of the second fuel to be allocated to each mission of the plurality of missions, the first fuel and the second fuel having one or more fuel characteristics different from each other, the method comprising:

determining one or more utility values for each mission of the plurality of missions, wherein the or each utility value for each mission is based on the same one or more of a predicted contrail outcome and a predicted local air quality outcome;
determining an ordering of the missions of the plurality of missions based on the or each utility value of each mission;
and
determining the overall fuel allocation for the plurality of missions based on the ordering of the missions.

1 more element

A fuel allocation determination system for determining an overall fuel allocation for a plurality of missions carried out by one or more aircraft, the plurality of missions being supplied with fuel from a fuel source comprising an amount of a first fuel and an amount of a second fuel, the overall fuel allocation indicating an amount of the first fuel and an amount of the second fuel to be allocated to each of the plurality of missions, the first fuel and the second fuel having one or more fuel characteristics different from each other, the system comprising:

a utility value determination module configured to determine one or more utility values for each mission of the plurality of missions, wherein the or each utility value for each mission is based on the same one or more of a predicted contrail outcome and a predicted local air quality outcome and each utility value for the plurality of missions is based on the same one or more of the predicted contrail outcome and the predicted local air quality outcome for the respective missions;
and
a fuel allocation determination module configured to determine the overall fuel allocation for the plurality of missions based on the or each utility value for each mission.
