Definitions
- the present invention relates to the field of air or sea control. More specifically, it relates to systems and methods for assisting the avoidance of collisions between aircraft or ships.
- the present invention therefore aims to overcome the aforementioned drawbacks.
- the invention proposes a device for assisting in the avoidance of a detected conflict in a predetermined horizon of trajectory prediction, between a first trajectory of a first aircraft and a second trajectory of a second aircraft or between a first trajectory of a first ship and a second trajectory of a second ship.
- Figure 1 shows a device according to the invention.
- FIG. 2 represents the loss of horizontal separation distance between a first aircraft and a second aircraft.
- FIG. 3 represents a potential conflict between a first aircraft and a second aircraft.
- Figure 4A shows a peripheral side shell according to the invention.
- 4B represents another implementation of the peripheral lateral envelope according to the invention.
- Figure 5 shows a division of the peripheral lateral envelope of Figure 4A.
- FIG. 6 represents an example of a first aircraft diversion in the peripheral lateral envelope of FIG. 5, according to the invention.
- FIG. 7A represents an evaluation of the possible diversions starting from FIG. 6,
- FIG. 7B represents a conflict avoidance surface obtained from FIG. 7A, according to the invention.
- FIG. 8 represents two conflict avoidance surfaces obtained from FIG.
- Figure 9 shows a flow chart of a method according to the invention.
- the elements shown are not to scale with respect to each other unless otherwise indicated.
- the general principle of the invention is based on the fact that in practice, an air traffic controller or a maritime controller globally solves the anomalies of its traffic by seeking to minimize the number of interventions.
- a conflict namely a loss of separation distance, between one or more aircraft or ships is a major anomaly.
- the objective for a controller in charge of a portion of the traffic constituted by a volume / responsibility space is to minimize the changes on the traffic.
- the search for a solution to a conflict will primarily concern aircraft or ships considered anomalous.
- the operator will therefore treat each anomaly unitarily while providing solutions for overall traffic fluidification.
- a solution is proposed that follows this sequential approach, that is to say that one aircraft or ship is treated at one time.
- the computation time will be reduced compared to a global optimization method, because it optimizes the navigation trajectory of a single aircraft or ship at a time while ensuring coherence with the overall traffic.
- it is proposed to determine for each aircraft or ship handled, at least one conflict avoidance zone, in which a diversion of the trajectory of the aircraft or ship avoids the conflict.
- the controller chooses between several conflict avoidance trajectories in order to implement the traffic flow strategy that seems most suitable for the current traffic. In doing so, the controller has a mechanism to assist in the development of a regulatory solution.
- the invention is also applicable to the maritime domain. In most cases it will be sufficient to replace the word aircraft with the word ship and the word air with the word maritime. The main difference between the two domains lies in the detection of three-dimensional conflict in the air and two-dimensional in the maritime domain.
- FIG. 1 illustrates a device 100 for assisting the avoidance of a potential conflict according to the invention.
- the potential conflict may occur, in flight, during en-route or approach. It should be noted that the invention may similarly be applied for a ground movement at the aerodrome.

- the positions of the aircraft 10, 20 do not respect a horizontal separation distance. D.
- the horizontal separation distance d between the trajectories of the first aircraft 10 and the second aircraft 20 is less than the predetermined horizontal separation distance D.
- FIG. 3 shows another example in which a first aircraft 30 is in potential conflict with a second aircraft 40.
- a potential conflict is defined by the detection of a loss of separation distance according to the predictions of the trajectories of the aircraft.
- it is provided, in a predetermined horizon of trajectory prediction, that the trajectories of the aircraft 30, 40 will not respect the predetermined horizontal separation distance.
- TCT Tactical Conflict Detection Tool
