Abstract: A procedure and device optimize the quantity of fuel transferred on an aircraft during at least one in-flight fuel transfer. The optimization device includes a section that makes a prediction to determine a first quantity corresponding to the quantity of fuel remaining on board the aircraft at a first flight point in the flight plan of the aircraft, taking into account the current status of the aircraft and the current flying conditions. The device further includes a section that makes an estimation to determine a second quantity corresponding to the quantity of fuel enabling the aircraft to fly from the first flight point to a second flight point later in the flight plan. The device further includes a section that determines, from the first and second quantities, a third quantity corresponding to the quantity of fuel to be transferred at the first flight point. The device further includes a display that presents the third duly determined quantity to at least one pilot of the aircraft.

Abstract: Disclosed is a method and device for guiding an aircraft flying along a flight trajectory. The flight trajectory has at least one constrained section, and the aircraft flies at a required speed within the constrained section to comply with a required arrival time at a predetermined waypoint in the constrained section. Auxiliary speed setpoints are determined to guide the aircraft to arrive at an auxiliary arrival tune at an auxiliary waypoint, with the auxiliary speed setpoints being applied by a guidance system to guide the aircraft.

Abstract: The invention relates to a method and device for aiding the management of successive flights of an aircraft. The device includes a determination unit which uses values recorded automatically for a flight, to automatically determine the values of characteristic parameters for waypoints of a next flight.

Abstract: Method and device for aiding the management of successive flights of an aircraft. The device (1) comprises means (3) which use values recorded automatically for a flight, to automatically determine the values of characteristic parameters for waypoints of a next flight.

Abstract: The device (1) comprises means (9, 11) for transposing a time constraint to entry to a constrained section of a flight trajectory having to be followed by the aircraft.

Abstract: The device (1) comprises first means (2) for defining a main trajectory, which is followed by the aircraft, and an optional trajectory which deviates from the main trajectory, which exhibits at least one common point shared with said main trajectory and which is able to be followed by the aircraft if said trajectory is activated, second means (3) for automatically determining a decision point which indicates the last position of the aircraft along the main trajectory, where the optional trajectory can still be activated so as to allow the aircraft to follow it, third means (6) for automatically presenting the decision point to a pilot of the aircraft, and fourth means (9) which are actuatable, allowing a pilot to activate said optional trajectory.
