Definitions
- the present invention relates to a control support system, a control support method, and a control support program that support a controller by displaying the status of an aircraft when it is assumed that a conflict avoidance plan has been adopted.
- a conflict is a situation in which two aircraft navigating at the same altitude are closer than the distance (offshore control interval) set to ensure safety.
- an avoidance plan for changing the state of the aircraft is created in order to avoid the conflict.
- the controller selects an evasion plan and instructs the aircraft according to the evasion plan.
- One workaround represents a change in the speed or altitude of a single aircraft. Therefore, it can be said that one aircraft corresponds to one avoidance plan.
- Patent Documents 1 and 2 Various devices for supporting the controller have been proposed (see, for example, Patent Documents 1 and 2).
- the apparatus described in Patent Literature 1 creates an avoidance plan for avoiding a conflict, and displays each avoidance plan in an order based on the priority of each avoidance plan.
- Patent Document 2 extracts aircraft existing within a certain range and displays those aircraft in a three-dimensional display.
- JP 2012-118697 A paragraphs 0027, 0030 to 0033, etc.
- JP 2000-276700 A first page, paragraph 0058, FIG. 4 etc.
- the controller must select one of the avoidance plans and give an instruction according to the avoidance plan to the aircraft corresponding to the avoidance plan.
- the controller must again select the evasion plan. Therefore, when the controller selects an avoidance plan and issues an instruction to an aircraft corresponding to the avoidance plan, it is preferable that the controller can easily determine the number of other aircraft that will approach the aircraft in the future.
- the variety of other aircrafts that will approach the aircraft corresponding to the evasion plan in the future represents the reliability of the evasion plan in the future. That is, it can be said that the smaller the number of other aircraft approaching the aircraft corresponding to the avoidance plan in the future, the higher the reliability of the avoidance plan, and the more other aircraft approaching in the future, the lower the reliability of the avoidance plan.
- Patent Document 1 displays each avoidance plan in the order based on the priority of the avoidance plan.
- this priority is set based on a standard different from that of other aircraft that will approach the aircraft corresponding to the avoidance plan in the future.
- the system described in Patent Document 2 displays a three-dimensional stereoscopic display of an aircraft existing within a certain range.
- This display result indicates the congestion status of the aircraft at a certain point in time. Therefore, when the controller wants to grasp the future congestion situation, it is necessary to designate a certain point in the future and confirm the 3D stereoscopic display result at that point. At this time, the controller can only grasp the congestion situation at a certain point in the future. Therefore, when the controller wants to grasp the congestion situation in the time zone from now to the future, the controller must specify the individual time in the future and confirm the three-dimensional stereoscopic display result. This increases the burden on the controller.

For example, if the transformation matrix calculation unit 3 calculates the transformation matrix in order from a two-dimensional vector starting from the FIX where the machine of interest passes the earliest from the current time, the obstacle figure calculation unit 2 determines that the machine of interest is from the current time. What is necessary is just to create each link after the link which uses the FIX which passes the earliest as a starting point.

Then, the route information display processing unit 4 specifies a point determined by a combination of the time when the aircraft of interest after the state change based on the avoidance plan passes each FIX and the position on the x-axis specified as the position of the FIX. The route information display processing unit 4 displays the x-axis and the t-axis, and displays a line (reference line) connecting these points on the display unit 5. At this time, the route information display processing unit 4 displays the ellipse specified from the sampling point on the display unit 5 based on the sampling point of the ellipse on the xt plane obtained in step S3 (step S4).

- One ellipse corresponds to one peripheral aircraft.
- the controller refers to the screen displayed in step S4 and, based on the number of ellipses 15 and the distance between the ellipse 15 and the reference line 11, the conflict after the air traffic control is performed according to the selected workaround. Ease of occurrence can be confirmed.
- the controller can determine the reliability of the selected avoidance plan in the future from the viewpoint that the smaller the number of ellipses 15 is, the better.
- each ellipse 15 does not belong to the range surrounded by the lines 12 and 13 (see FIG. 1).

Therefore, the display screen in step S4 represents not only the situation at a certain time in the future, but also the proximity situation between the aircraft of interest and the peripheral aircraft in a wide time zone. Therefore, the controller does not need to specify each individual time in the future, and can understand at a glance the proximity situation between the aircraft of interest and the peripheral aircraft in the future time zone.
- the controller selects another avoidance plan. Then, the control support system 1 executes steps S1 to S4 for the avoidance plan. Then, the controller may adopt a reliable avoidance plan for the future and give instructions to the aircraft of interest according to the avoidance plan.

The method for calculating the ellipse in the three-dimensional space is the same as in the first embodiment.
- the end point time of the link FB is delayed by p. Further, the x coordinate and the y coordinate of the end point of the link FB are not changed. For this reason, the oblique column body corresponding to the link of the peripheral device after the change is higher than the oblique column body shown in FIG. In addition, the angle formed by the oblique column body and the xy plane also increases. Accordingly, the size and shape of the ellipse determined by the intersection between the oblique column and the plane H 0 (see FIG. 3) also change. In this example, the inclination of the ellipse with respect to the xy plane is increased, and the length of the ellipse in the major axis direction is increased.

- the ellipse 16 shown in a display mode different from the ellipse 15 (specifically, the ellipse 16 displayed with a dotted line) is a combination of the link when the FIX passage time of the peripheral aircraft is changed and the link of the aircraft of interest. It is an ellipse on the xt plane obtained based on this.

- the ellipse 16 is closer to the reference line 11 than the ellipse 15 by changing the FIX passage time of the peripheral aircraft. Therefore, as specified by the controller, it can be seen that the reliability of the avoidance plan selected by the controller decreases when the situation of the peripheral aircraft changes.
- FIG. 3 The control support system according to the second embodiment of the present invention can be expressed by the same configuration as that in FIG. 2, and the third embodiment will be described below with reference to FIG.
