Abstract: A method sharing data between aeronautical equipment items. At least one equipment item is included in an aircraft carrying out a flight mission. The method includes obtaining a set of data coming from said equipment item. The method further includes adding of the set of data to a common group including data common to all aeronautical equipment items. The method incudes filtering the data of the common group in order to determine at least one first relevant datum for successfully completing the flight mission. The method incudes transmitting, to at least one other equipment item, of only the at least first relevant datum to be used for a display to a respective user, or for a computation, of a command of the aircraft.

Abstract: Systems and methods for improved human-machine dialog, include bidirectional translations notably through the translation of commands by the human into a form able to be manipulated by the machine, and conversely of results produced by the machine into a form intelligible to the human. Some developments describe notably the display of portions of intermediate reasoning followed by the machine (for example explanation of root causes).

Abstract: This method for determining at least one fuel cosumption domain for an aircraft is implemented by an electronic device. It comprises acquiring a flight envelope as a function of the altitude and a propulsion variable. It comprises, for at least one flight phase, calculating a consumption limit curve as a function of the altitude and the propulsion variable, corresponding to a forecasted average consumption for said flight phase; and determining—from the flight envelope and the limit curve—the consumption domain as a function of the altitude and the propulsion variable and including a first consumption subdomain lower than the forecasted consumption for said flight phase and a second consumption subdomain greater than said forecasted consumption, the first and second subdomains being separated by the limit curve.
