Abstract: A method for managing a longitudinal position a follower aircraft following a leader aircraft by: obtaining a position and speed of the leader aircraft and a real longitudinal position and speed of the follower aircraft; determining a target longitudinal position of the follower aircraft with respect to the longitudinal position of the leader aircraft; calculating a difference between the target longitudinal position of the follower aircraft and the real longitudinal position of the follower aircraft; comparing the value of the difference with at least one predefined threshold; choosing a control law for controlling the speed of the follower aircraft, from among at least two separate control laws, on the basis of the comparison; and, applying the chosen control law so as to manage the real longitudinal position of the follower aircraft with respect to the position of the leader aircraft.

Abstract: A system for assisting formation flight, on board a follower aircraft, determines an estimated position of a wake vortex generated by a leader aircraft and inducing an upward airflow. The system determines a first trajectory, intended to be followed by the follower aircraft, as a trajectory for approaching and tracking the wake vortex, while remaining outside a potential discomfort window. The system determines a second trajectory corresponding to a phantom aircraft as if the follower aircraft is permanently in an optimal position relative to the wake vortex. The system assesses future overshoots of the phantom aircraft relative to maneuvering capabilities of the follower aircraft and to passenger comfort rules. The system possibly modifies the first trajectory as a function of the assessed overshoots.

Abstract: A formation flight assistance system is placed on board a follower aircraft to benefit from an upwards air flow induced by a wake vortex generated by a leader aircraft. The system determines a wake vortex effect experienced by the follower aircraft as being a difference between measurements taken by sensors and modelling in a wake vortex free environment. Using a recursive Bayesian filter, the system determines an estimated position of the wake vortex on the basis of information relating to the leader aircraft and a wake vortex model, and determines an estimation uncertainty, according to which a potential discomfort window is computed for the passengers of the follower aircraft. The system keeps the follower aircraft outside the potential discomfort window. Thus, the comfort of the passengers of the follower aircraft is provided, while benefiting from an upwards air flow induced by the wake vortex.
