1. An aircraft operational flight plan establishing system, comprising:
a basic flight data acquisition unit configured to acquire basic flight data from an external flight plan development system, the basic flight data comprising at least one theoretical fuel weight to be loaded into an aircraft;
an aircraft actual operational specifications acquisition unit configured to acquire actual operational specifications of the aircraft intended to perform the flight according to an operational flight plan, the actual operational specifications including an airplane context;
a proposed flight data calculating unit configured to calculate, before the flight, proposed flight data including at least one proposed total weight of fuel corresponding to the at least one theoretical weight, the proposed flight data being calculated based on the actual operational specifications of the aircraft and on at least one specified trajectory of the aircraft;
a viewer, and a display manager on the viewer, configured to display, on the viewer, a proposed flight data display window including at least the proposed weight of fuel,
wherein the aircraft actual operational specifications acquisition unit is configured to acquire defect, failure and/or dispatch data from the aircraft, the airplane context including structural data relative to the aircraft and/or the defect, failure and/or dispatch data of the aircraft,
wherein the proposed flight data includes a weight at takeoff or landing of the aircraft on a given terrain, the proposed flight data calculating unit being configured to compute the weight at takeoff or landing of the aircraft on a given terrain, using a low-speed performance determining application configured to determine a maximum weight of the aircraft allowing the aircraft to take off and/or land on the given terrain based on the airplane context.
