Abstract: A method for guidance and for assisting in following a trajectory for velocity-vector piloting of an aircraft includes a step of calculating, at all times, lateral and vertical offsets of the current position of the aircraft from a target trajectory, estimated by a flight management system, and then a joining heading and a joining gradient for the aircraft to join the trajectory depending on these offsets; and a following fourth step of displaying, in head-up or head-down form, a consistent guidance symbol centered on the calculated joining heading and the calculated joining gradient for joining the trajectory, on a piloting screen showing a velocity vector. The fourth step may display, in addition to the guidance symbol, one or more items of information anticipating the next trajectory break.

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.
