    Abstract: A flight management unit includes two guidance subsystems each including a flight management system, each of the flight management systems being configured at least to extract a flight plan from at least one navigation database, to construct a flight trajectory, and to compute guidance commands for the aircraft. The flight management unit also includes at least one monitoring unit configured to compute a guidance command from a validated flight trajectory and a consolidated flight plan and to monitor the guidance command, as well as guidance commands computed by the two flight management systems so as to be able to detect and to identify a defective flight management system.

    Abstract: A method for generating an optimum vertical trajectory of a flight trajectory of an aircraft in the descent/approach phase. The trajectory is defined between a current state and a target state of the aircraft on the basis of a speed profile of the aircraft as a function of a curvilinear abscissa of the aircraft along a flight plan. The profile corresponds to a transition between the current and target states and is broken down into successive segments each corresponding to a different aerodynamic configuration that the aircraft may adopt during the descent/approach phase. The method is based on defining a set of flight strategies, each strategy of the set being defined using for each segment of the speed profile flight parameters chosen randomly in ranges of values compatible with the aerodynamic configuration corresponding to that segment. Optimum vertical trajectory is generated on the basis of the strategy of the set.

    Abstract: A flight management system for an aircraft and method of securing open world data using such a system. The flight management system includes at least two flight management computers including one computer termed active forming part of an active guidance subsystem configured to supply data for guiding the aircraft. Another computer is termed inactive at the current time. The flight management system includes a validation subsystem that includes the inactive flight management computer and a validation unit connected to the flight management computers. The validation subsystem is independent of the active guidance subsystem and configured to validate open world data and to transmit at least to the active flight management computer data that is validated during the validation.

    Abstract: A method and device for assisting in piloting of an aircraft in approach to a landing runway with a view to a landing, including a module for determining current state of the aircraft, a module for determining distance between a target state and current state from an approach strategy and an ellipse formed by points determined such that a sum of a distance between the current position of the aircraft and the points of the ellipse and of a distance between the points of the ellipse and a projection of the target position on a horizontal plane of movement of the aircraft is equal to distance between target state and current state. The ellipse is displayed on a screen. The ellipse form gives indicates significance and variation of the energy surfeit of the aircraft. The pilot can decide on actions to maneuver the aircraft appropriately to dissipate the excess energy.

    Abstract: A method and system for generating an optimized flight trajectory of an aircraft. The generation system includes a module for determining a long-term flight trajectory from an obstacle prediction model, a following module for the aircraft to fly by following the long-term flight trajectory and a module for updating the long term trajectory from a short-term trajectory as a function of characteristics of at least one obstacle detected during the following of the long-term flight trajectory by the aircraft and as a function of a predetermined risk criterion threshold. The generation system makes it possible to generate a flight trajectory that avoids obstacles simply and reliably.
