METHOD AND SYSTEM FOR CONTROLLING THE FLIGHT OF AN AIRCRAFT SUBJECTED TO AT LEAST TWO REQUIRED TIME OF ARRIVAL CONSTRAINTS

摘要

The invention discloses a method and a system for controlling the flight of an aircraft subjected to at least two required time of arrival constraints. It comprises receiving at least two required time of arrivals (RTA_n), each required time of arrival (RTA_n) at a corresponding target waypoint (WPT_n) wherein at least one target waypoint is located in a descent phase of the flight; determining a set of cruise/descent speed pairs for each one of the RTA wherein each pair satisfies the corresponding RTA_n at the corresponding WPT_n, the cruise speed and descent speed of each pair being calculated independently from each other; selecting a single cruise/descent speed pair existing in each one of the sets of cruise/descent speed pairs; and determining a single aircraft trajectory that satisfies the selected cruise/descent speed pair.
