- a flight plan 30 (FPLN) is filed, to inform the air navigation services. This contains all of the information specified about the intended flight or part of the flight, including:
- the flight plan between a starting point and a destination point to reach contains a set of waypoints (in English "waypoints" 5 (WPT)) ordered in a predetermined manner, where at each waypoint, a change of heading or altitude or speed must take place.
- a waypoint is defined by a geographic position, latitude, and longitude coordinates. All these points can be chosen from predefined points in a navigation database, which can correspond to airports, radio navigation beacons, etc.
- the FMS is an on-board navigation aid system, which incorporates information on aircraft performance and position, information from navigation sensors, 15 from the flight plan that is stored, and manual entries. Its purpose is to assist pilots, by providing via a suitable man-machine interface, piloting instructions, or to allow automatic guidance of the aircraft along the trajectory when it is coupled with the autopilot.
- the FMS uses different sensors 20 to determine the current position of the aircraft (PPOS) and the accuracy of this position. Precision is defined as the degree of conformity between the estimated, measured or desired position and the actual position of the aircraft at a given time.
- the FMS also allows the pilot to modify the flight plan, during the flight, for various reasons such as a delay induced by bad atmospheric conditions to be avoided, or by requests imposed by the air traffic control units (ATM).
- ATM air traffic control units
- the FMS calculates a lateral trajectory. From the cruising level and the altitude constraints, the FMS also calculates a vertical profile. From the speed constraints and the optimized speeds of each flight phase and according to a cost index which is chosen by the airline, the FMS calculates a speed profile. Taking into account the flight plan and the position of the aircraft, the FMS calculates the reference trajectory to follow, which is a succession of straight and curved segments. The points connecting the segments of the reference trajectory may correspond to waypoints of the flight plan 35 or be different.
- Figure 1 illustrates a portion of a lateral trajectory between a position initial, illustrated in the example by a point corresponding to the current position (PPOS) of the aircraft, and a final position, illustrated by a final waypoint WPT f .
- Each point of the flight plan (WPT ! , WPT 2 , ..., WPT ,, ..., WPT f ) is represented on the portion considered by a diamond.
- the intermediate points 5 (T 1; T 2 , ..., T ,, ..., T m ) of the reference trajectory are represented by solid circles.
- Optimizing a trajectory consists in finding a trajectory that minimizes costs by considering the price of fuel, operating costs, delay in arrival costs, overflight costs, 10 weather conditions (temperature, atmospheric pressure, wind speed and direction, disturbances, etc.), prohibited areas (military areas, turbulence, etc.) and speed and altitude limits in certain regions.
- the present invention provides a method allowing an automatic search for shortcuts taking into account any type of point, points on a reference trajectory and / or points on a flight plan. , and allowing to determine the combination of several shortcuts making the trajectory optimal.
- 25 - R3 illustrates a shortcut between a point of the flight plan WPT 8 and an intermediate point Ti of the reference trajectory
- a shortcut of type R1 between the current PPOS position of the aircraft and a point in the flight plan corresponds to a segment which can be activated by the functionality known as the “DIRTO” of an FMS, allowing direct joining from the current position to the waypoint located downstream.
- An R2 shortcut between two points in the flight plan corresponds to a segment which can be activated by the functionality known as “NEXT WPT” of an FMS, making it possible to fly directly from one waypoint to another. waypoint located downstream.
- the general method of the invention as illustrated in FIG. 2, allows in a first step (202) to determine all the paths existing between an initial point and an end point by considering the combination of all 15 possible shortcuts; then to calculate (204) the costs generated by the different paths; and then to determine (206) the path ("optimal path") minimizing the cost of the trajectory according to a chosen optimization criterion.
- the method displays (208) the 20 results - the optimal path and the gains obtained.
- the results are displayed on an interface on board the aircraft in the form of a trajectory, for example for the optimal path.
- a display interface may include one or more display screens.
- the invention makes it possible to take advantage of modern, reliable, robust man-machine interaction systems, and according to embodiments, the display means can be touch screens, force feedback, augmented reality. and / or virtual.
- the display means may include or implement one or more devices such as virtual reality headsets and / or augmented reality glasses (eg "head-mounted 30 display”, “wearable computer”, “glasses” or a head-mounted display) and / or projection devices (eg holographic).
- a virtual reality headset worn by a pilot can be opaque or semi-transparent or with configurable transparency.
- the display can be "high sight”.
- the information can be displayed in one or more virtual and / or augmented reality headset (s).
- the information can therefore be entirely virtual (displayed in an individual helmet), entirely real (for example projected on the flat surfaces available in the real environment of the aircraft cockpit) or a combination of the two (partly a virtual display superimposed or merged with reality and partly a real display via projectors).
- the display can also be characterized by the application of predefined location rules and display rules.
- human-machine interfaces or information
- can be "distributed" can be "distributed" (segmented into separate portions, possibly partially redundant, then distributed) between the different virtual or real screens.
- the pilot or operator can select the new proposed trajectory.
- the pilot can choose either a single optimization criterion (Fuel; Time; Distance) or a more complex function taking into account different costs (Fuel + Cost x Time Index).
- An optimal trajectory must avoid existing obstacles in an airspace, taking into account one or more given metrics (time, distance, fuel consumption, etc.). It is generally considered that an airspace contains critical areas such as areas with bad weather or congested areas, that is to say areas 20 with heavy traffic.
- the optimization of a trajectory according to the method of the invention permanently takes into account all the constraints which will impact a mission, whether these are fixed constraints (criteria of an airline company or a customer, aircraft characteristics and performance), constraints linked to ATM (taxes, characteristics, structures, rules 25 of air traffic control organizations (ATC) in the various sectors, etc.) or evolutionary constraints such as those linked to the environment (weather conditions, traffic congestion, overflight zones prohibited) and the uncertainties about the forecast of its evolution.
- the method of the invention makes it possible to calculate and propose optimized trajectories which are:
- FIGS. 3a to 3e detail the step (202) of determining all the possible paths in a search area (302), for a portion of a lateral trajectory between an initial position, taken as the current position of a aircraft (PPOS) for the example described, and a final position WPT f .
- a search area can correspond to different spaces, such as for example:
- FIGS. 3a to 3e they illustrate the steps for the construction of a path graph, the graph comprising a set of nodes and arcs representative of all the paths with possible shortcuts, calculated from the data of the flight plan. , a reference trajectory and 20 fixed constraints.
- the graph makes it possible to represent all the possible paths which are composed of combinations of shortcuts.
- the input data of step (202) consist of a list of waypoints from the initial flight plan, a list of segments (straight and curves) of the reference trajectory, a step of 25 discretization to apply and static constraints.
- the static constraints to take into account generally include:
- starting point latitude, longitude, altitude, time, weight
- arrival point latitude, longitude, altitude, time, 30 weights
- Such areas can be represented by 35 3D polygons (which can represent closed areas, for example).
- the method of the invention in the initial step (202) makes it possible to generate a graph the nodes of which represent crossing points between a starting point and an ending point.
- the nodes can be either points of the flight plan, or intermediate points of the reference trajectory.
- the arcs of the 5 graph represent the possible shortcuts between the points, in the search area. In one embodiment, it is possible to select and limit the types of shortcuts to take into account for the construction of the graph.
- the method begins for an initial search area (302) between an initial position, here the current position of an aircraft (PPOS) and a final position WPT f by considering the set static constraints.
- PPOS current position of an aircraft
- the method allows the search area to be discretized, to discretize the trajectory according to a (pre) defined discretization step, and to calculate the geographical position of the intermediate points of the trajectory corresponding to the discretization step.
- a discretized trajectory (304) is generated comprising the points of the flight plan and the intermediate points of the trajectory.
- the method makes it possible to determine, for the discretized trajectory, all the possible paths (306), firstly without excluding paths from the zones to be avoided.
- the method makes it possible, starting from the first point of the discretized trajectory, to create a first shortcut to the next point of the discretized trajectory and corresponding to one of the types of possible shortcuts. 25
- the method repeats the search for shortcuts from the first point to each of the other following points of the discretized trajectory, and this up to the final point, thus making it possible to generate for the first point, a first in seemingly paths with all type of shortcuts, connecting the first point to all the following points of the discretized trajectory.
- the method then makes it possible to pass to the next point of the discretized trajectory, and to apply the same iterative process of connecting the second point to all the other following points of the discretized trajectory, making it possible to generate a second set of paths connecting the second point at all the following points of the discretized trajectory.
- the process is repeated for all points (except the end point) of the discretized path.
- the method makes it possible to delete all the paths which intersect with areas to be avoided (308) (ie taking into account the evolutionary constraints), and thus generate as illustrated in FIG. 3e, a graph which includes only possible paths with shortcuts (310 ) between the start point and the end point WPT f .
- FIG. 4 details the step (206) of determining the optimal path among all the possible paths which were identified in the previous step (202).
- this step consists in applying a shortest path algorithm with propagation of predictions on the graph 10 generated in the previous step. Prediction calculations are made during the course of the graph, and a predictive state of the aircraft and an associated cost at each point are estimated at each point.
- the algorithm applied can be one of the shortest path algorithms known as Dijkstra or A * or Bellman-Ford to name only these examples.
- the proposed solution makes it possible to consider a set of paths defined by a graph and to propose the optimal path for an aircraft from one node to another node in this graph, that is to say the least expensive path according to the chosen optimization criteria (flight time or distance or fuel consumed 20 or a combination of these criteria), while considering the dynamic constraints.
- the dynamic constraints can be:
- 25 tives eg ATC sector saturation, military threat zones such as radar detection
- the general principle is that at each iteration, the method attempts to approach the end point of the destination and will favor the possibilities which are directly closer in terms of the cost of the destination, putting aside all the others. All other path possibilities which do not allow you to approach the destination are set aside, but are not deleted. They are put into a list of possibilities to explore if the solution currently explored turns out to be bad. Indeed, it is not possible to know in advance if a path will succeed or be the least costly. If this path leads to an impasse, the solution becomes unusable.
- the algorithm implemented will first analyze the least expensive paths. If these paths do not succeed or else prove to be unusable subsequently, the method makes it possible to examine the solutions put aside. Advantageously, by going back to examine the solutions put aside, it is guaranteed that the algorithm will travel all the possible paths to find an optimal solution "said solution path"
- the method uses two lists which contain graph nodes as well as associated cost and prediction values.
- the first list called “open list” will contain all the nodes of the graph to be studied. As soon as the algo rithm operates on a node of the graph, the latter is put in the open list (unless it is already there).
- the second list called “closed list”, contains all the nodes which, at one time or another, were considered to be part of the solution path. This closed list is used to reconstruct the path of the solution chosen. Before going into the closed list, a node must first go into the open list, because indeed, it must first be studied before being considered as a good candidate for the optimal solution.
- each node has a parent, which in this case is the ‘optimal ’node by which the algorithm arrived before the current node considered.
- a parent node represents the best path between two nodes.
- the parent node is very important at the end of the algorithm, in order to find the optimal path by going backwards through the closed list of parent nodes.
- a current node is the grouping of the following information:
- 35 - attributes of the current node fixed attributes (3D position, distance, etc.) and predicted attributes (fuel, time, etc.).
- the method To determine if a node is likely to be part of the solution path, the method must quantify the three values G, H and F as well as the predicted attributes. The method makes it possible to analyze each of the nodes neighboring the current node to determine which one is more likely to be part of the solution path.
- the search for the path begins with a first node by studying all of its neighbors; by calculating the different costs G, H and F, and choosing the best one to continue.
- Each node studied is put in the open list and the best of this list goes into the closed list; it will be used as a base (parent node) for the next search.
- the process makes it possible to look among all the nodes which have been studied (and which have not yet been chosen) which one has the best quality (minimum cost ‘F ’).
- the algorithm stops when the destination has been reached with the lowest cost value 'F' among all the nodes or when all the solutions put aside (open list) have been studied and none of them 'has been shown to be good (if there is no optimal solution).
- the method will reconstruct the path each time following the parent nodes present in the closed list, and go up the thread until arriving at the starting parent node.
- Step (406) select the lowest cost node as the node to be studied
- Step (410) calculate for each next node of the node to be studied, the predictions and the different costs G, Fl, F;
- Step (415) update the cost and prediction information for the node of the open list, and update the parent of this node by
- Step (422) when all the nodes have been studied (empty open list), the process ends with no optimal solution found.
- FIG. 5 illustrates a structure of a flight management system making it possible to implement the method of the invention.
