Abstract: Method and device for aiding the guidance of an aircraft having to comply with at least one time constraint. The device can determine and present on a screen of the flight deck an offset in distance (?D) between the aircraft (AC) and a reference aircraft (Aref) which is defined to fly along the flight plan (TV) at an optimal speed to comply with the time constraint.

Abstract: A system for automatically modifying a lateral flight plan of an aircraft includes modifying means adapted to modify the flight plan by an action to chosen among the following actions: deleting, adding and moving at least one waypoint of an initial flight plan (T1). The modified flight plan (T3) includes one downstream waypoint (P6) defined as the waypoint on which the aircraft gets back to the initial flight plan (T1), and one upstream waypoint (P4) preceding the downstream waypoint (P6). By defining an intermediate point (P5?) between the upstream (P4) and downstream (P6) waypoints, the coordinates are calculated in order to allow the aircraft to reach the downstream waypoint (P6) with the same course as the initial flight plan (T1).

Abstract: A method and device for displaying the performance of an aircraft when climbing and/or descending. The device includes devices for data capture, calculation and generating images for a display screen. The calculation device is configured to calculate a maximum slope that the aircraft can adopt depending on current data received from a data capture device. A display device presents images of the maximum slope superimposed with altitudes of a projected flight plan.

Abstract: The vertical profile management device includes a flight management system unit that selects a plurality of successive standard cruise sections, each comprising a level phase and a transition phase. The cruise sections are defined by a plurality of features, including waypoints corresponding to a section starting point and a section ending point, a transition type, a transition mode, a transition speed, a level altitude, and a level speed. The flight management system unit also joins together the successive cruise sections in order to form a vertical profile of a flight plan. The cruise sections are configured to be added, removed, or re-sequenced in the flight plan because each section ending point is configured to be the section starting point of a next cruise section in the series.

Abstract: A time constraint checking device performs a method for checking whether an aircraft is able to fulfill a plurality of successive time constraints corresponding to required times of arrival at a plurality of corresponding waypoints. The method includes comparing, for each of the waypoints, a comparison value depending on the time constraint with either an estimated time of arrival or minimum and maximum possible times of arrival based on speeds of the aircraft. The method performs different comparisons depending on whether the time constraints for a particular waypoint are a single time value or a time window, and an optimized time of arrival for meeting all future time constraints is also possible.

Abstract: Disclosed is a method and device of guiding an aircraft along a flight trajectory to comply with a time constraint for arriving at a required arrival time at a waypoint of the flight trajectory. Speed setpoints are determined according to a speed profile that complies with the required arrival time at the waypoint, based on estimated values of parameters relating to the flight of the aircraft, and by taking account of an upper limit for a maximum speed at which the aircraft flies along the flight trajectory. The determined speed setpoints are applied to the aircraft during guidance of the aircraft along the flight trajectory.
