1. An aircraft mission calculation system, comprising:
a trajectory calculation engine configured to calculate trajectories of an aircraft during a mission, the trajectory calculation engine being configured to calculate at least one potential mission trajectory between a geographic point of origin and a geographic point of destination as a function of aircraft performance, mission operational specifications, and as a function of a meteorological context in a mission volume between the geographic point of origin and the geographic point of destination,
the mission calculation system being configured to activate the trajectory calculation engine to determine a first reference trajectory from first mission operational specifications defining a fastest mission between the geographic point of origin and the geographic point of destination, and to determine a second reference trajectory from second mission operational specifications defining a mission that minimizes an amount of carbon dioxide produced during the mission,
the mission calculation system being configured to calculate a first amount of carbon dioxide that would be produced by implementing the first reference trajectory, a second amount of carbon dioxide that would be produced by implementing the second reference trajectory, and a potential amount of carbon dioxide that would be produced by implementing the potential mission trajectory and to determine an environmental benefit index of the potential mission trajectory from the first amount of carbon dioxide, the second amount of carbon dioxide, the potential amount of carbon dioxide, and from a correlation function relating the amount of carbon dioxide produced to the environmental benefit index; and
a display, and a display manager configured to display on the display, after calculation of the potential mission trajectory by the trajectory calculation engine, at least one environmental benefit indicator derived from the environmental benefit index.
