摘要:
A flight management system for an aircraft, for executing a flight plan comprising referenced waypoints comprising a start point, an end point and intermediate waypoints, the said aircraft having a specified fuel quantity at the start of the said flight plan, executes a function of monitoring the fuel consumption with respect to at least one threshold value. The function comprises an operation for estimating if the quantity of fuel remaining on board drops below a threshold at any point in the flight plan included between the start point and the end point, and inserts a corresponding pseudo-waypoint in the flight plan, corresponding to the point where the said threshold is passed. The inserted pseudo-point is displayed on screens for displaying the flight plan.

Method of formulating a lateral flight trajectory for the rejoining by an aircraft (200) of a trajectory of a flight plan (910) comprising a plurality of waypoints (911, 912, 913), the aircraft (200) flying outside of the flight plan (910) and according to a divergent track with respect to the trajectory of the flight plan (210), characterized in that the method: determines a waypoint (913) of the flight plan for the rejoining, defined as the first waypoint (913) of the flight plan included in a capture zone defined by the flight plan trajectory situated downstream of the point of intersection between the straight line defined by an angle (α) with the perpendicular to the track of the aircraft and the trajectory of the flight plan, formulates the optimal lateral flight trajectory for a rejoining by the aircraft (200) at the determined waypoint. Advantageously, the flight trajectory formulation method allows the application of speed and/or altitude constraints to the aircraft (200) taking into account speed and/or altitude constraints imposed along the trajectory of the flight plan (910).

摘要:
Flight management system for aircraft comprising computation means capable of determining a gain or a loss in terms of flight time remaining to a point of arrival, and in terms of fuel consumption, following the input by an operator of a modification of an initial flight plan using the Direct To function. The computation means are capable of suggesting to the operator a modification of the lateral flight plan that procures an optimum gain. The flight management system also comprises a display interface capable of presenting to the operator the information concerning the gain or the loss in time and/or consumption, and of prompting the operator to accept or refuse the modification.
