Abstract: A system for managing flight parameters of aircraft is parametrized with overarching flight cost objectives. For a first flight, parameters of a cost function for the first flight are determined relative, respectively, to different cost factors. Flight parameters are optimized so as to minimize the cost function. Avionics of an aircraft carrying out the first flight are programmed with the flight parameters. On detecting an event in flight requiring the flight parameters to be revised, the parameters of the cost function are recalculated, as well as the flight parameters, and the avionics are reprogrammed accordingly. The method is repeated for at least a second flight, taking into account the effective contribution of the first flight to the overarching objectives, and so on. Thus, an airline can carry out overarching multi-objective optimization on its flights.

Abstract: A method and a device for accessing the documentation of an aircraft according to alarms generated therein, where the documentation includes at least one document that is modifiable independently of the manufacturer of the aircraft. After having received at least one indication relating to at least one alarm generated by the avionics of the aircraft, at least one datum relating to the at least one alarm, including a link to at least one element of the documentation, is extracted and displayed.

Abstract: The invention in particular has as an object a method and a device for accessing the documentation of an aircraft according to alarms generated therein, the documentation comprising at least one document modifiable independently of the manufacturer of the aircraft. After having received (305) at least one indication relating to at least one alarm generated by the avionics of the said aircraft, at least one datum relating to the said at least one alarm, comprising a link to at least one element of the said documentation, is extracted (315) and displayed (325).
