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: Method and device for checking that an aircraft fulfils successive time constraints. The device comprises means for comparing, for waypoints (Pi-1, Pi), a comparison value depending on the required time of arrival (Ti-1A, Ti-1B) with minimum and maximum times of arrival based on constant speeds of the aircraft (AC).

Abstract: The device includes means for determining a plurality of successive standard flight sections (S1A, S2A, S3A, S4A) comprising a level and a transition phase for reaching this level, and means for joining together these successive flight sections (S1A, S2A, S3A, S4A) in order to form the vertical profile (PV1) of the flight plan.
