Abstract: A method and devices for machine learning applied to the mission trajectories of an aircraft are provided. Learning data comprise mission trajectories determined by an MMS mission computer and the corresponding avionic trajectories, such as those determined by certified avionic systems. Developments describe in particular steps of evaluation, e.g. use of cost function or mission score, optimization of the mission trajectories by means of evolutionary, in particular genetic, methods, the use of fuzzy logic, the display of intermediate results or other things for explanatory purposes. Software and hardware aspects (e.g. neural networks) are described.

Abstract: This avionics device intended to be on board an aircraft is configured to implement an avionics function and to control the display, by at least one receiving device, of data associated with the avionics function, the avionics function including one or several avionics commands able to be displayed on the receiving device and selected by a user. The avionics device comprises a module for generating a data message, and a module for sending said message to the receiving device. The generating module is configured to generate a usage domain message containing a list of avionics command(s) available for the corresponding avionics function, and the sending module is configured to send the usage domain message to the receiving device, to display the availability of the only command(s) included in said list.

Abstract: The message transmission method for transmitting a data message to at least one electronic receiving device, is implemented by a transmitting device. The transmitting device and the one or more receiving device(s) are connected via an avionics network, with the transmitting device and/or the receiving device being an avionics device. The transmission method includes the generation of a message, the message comprising a message header and one or more data packet(s); and the transmission of the message to the one or more receiving device(s). Each packet comprises one or more data cluster(s), each duster containing an identifier field, a size field and a payload data field, and each cluster is adapted to include one or more other data cluster(s), the one or more other data cluster(s) thus then forming the payload data field of said cluster.

Abstract: A method for assisting an aeronautical operator in the creation of a flight plan of an aircraft passing through a set of predetermined geographic mission zones includes a step of determination, for each mission zone, of an entry access point and an exit access point of the mission zone, the entry and exit access points associated with a mission zone being able to be separate or merged; and a step of determination of an interzone path from an entry access point to an exit access point of the set of the mission zones which connects, in series and without loop, all the mission zones by their entry and exit access points, and the length of which is minimal.
