The arriving aircraft position information extracting unit 12 is an external system, an ARTS (Automated Radar Terminal System).
m) or the current position information of each arriving aircraft is extracted from the information input from RDP (Radar Data Processing), etc.
Output to the landing time prediction unit 14.

The departure aircraft position information extracting unit 13 is an external system, SMGCS (Surface Movement Guidance and SMGCS).
The system extracts the current position information of each departure aircraft from the information input from the control system or the like, and outputs the information to the takeoff time prediction unit 15.

The landing time predicting section 14 predicts the scheduled landing time of each arriving aircraft based on the current position information of each arriving aircraft input from the arriving aircraft position information extracting section 12 and uses the estimated landing time information on the runway. Scheduled time allocation unit 16 and screen control unit 1
7 respectively. Note that the scheduled landing time is predicted based on the current position and speed of the landing aircraft, the contents of control instructions, a standard arrival profile, and the like.

The take-off time predicting section 15 predicts the scheduled take-off time of each departure aircraft based on the current position information of each departure aircraft input from the departure aircraft position information extraction section 13 and uses the estimated take-off time information on the runway. Scheduled time allocation unit 16 and screen control unit 1
7 respectively. The scheduled takeoff time is estimated based on the shortest taxiing route from the current position of the departure aircraft to the runway, a standard taxing speed, a standard pushback time, a scheduled flight plan start time, and the like. .

The scheduled runway use time allocating unit 16 allocates the scheduled runway use time based on the scheduled arrival or departure time information of each aircraft, sums up the delay times for the flight plans of each aircraft, and totals the total delay time. And outputs the runway scheduled time information and the total delay time information to the screen control unit 17. When the reservation of the scheduled runway use time is confirmed, the reservation confirmation information is output to the control instruction specifying unit 20.

The screen control unit 17 receives scheduled landing time information for each arriving aircraft from the landing time prediction unit 14, scheduled departure time information for each departure aircraft from the takeoff time prediction unit 15, and a scheduled runway use time allocation unit 16. For the aircraft, the scheduled runway use time information and the total delay time information and the information related to the control instruction from the control instruction specifying unit 20 are displayed so that the controller can easily grasp the information, and output to the display device 18. Further, pointing device operation information is input from the screen operation unit 19, and a change in the scheduled runway use time is output to the scheduled runway use time allocation unit 16.

The display unit 18 inputs display information from the screen control unit 17, cursor information of the pointing device of the screen operation unit 19, and the like, and outputs them to the display screen.

The screen operation unit 19 uses a pointing device such as a mouse, for example, to move a cursor on the display screen and to perform designation input by clicking.

The control instruction specifying unit 20 receives the reservation confirmation information from the scheduled runway use time allocation unit 16 and, in the case of an arriving aircraft, transmits the control instruction contents and the control instruction such that the aircraft symbol and the reservation slot become parallel. After the transmission timing (time) is specified, information on the control instruction is output to the screen control unit 17.

The processing operation of the above configuration will be described with reference to a screen display example serving as a user interface part with the controller shown in FIG.

In FIG. 2, the upper region shows the scheduled take-off time of each aircraft calculated by the take-off time prediction unit 15, the lower region shows the scheduled landing time of each aircraft calculated by the landing time prediction unit 14, and The section area indicates the scheduled runway use time of each aircraft calculated by the scheduled runway use time allocation unit 16.

Here, the aircraft symbols shown in the upper and lower areas of the screen are defined as shown in FIG. That is,
The symbols of aircraft to be controlled shall be painted out, the symbols of aircraft not to be controlled shall be displayed in transparent dotted lines, the symbols of aircraft selected on the screen shall be displayed in outline, and the aircraft flight number shall be displayed below each symbol. And

As a method of expressing the scheduled runway use time shown in the center area of the screen, a slot display as shown in FIG. 4 is performed. In the figure, the upper part is the slot display column of the departure aircraft, and the lower part is the slot display column of the arrival aircraft. In these slots, reserved slots at the scheduled runway use time are painted out, and unreserved slots are transparently displayed for identification. Each slot indicates an aircraft flight number and a wake turbulence classification. In the reserved slots, the upper length indicates the minimum required distance between departures and the lower length indicates the minimum required distance between departures and arrivals.
In the unreserved slot, the upper length indicates the minimum required interval between the arrival machine and the departure aircraft, and the lower length indicates the minimum required interval between the arrival aircraft. The method for reserving the scheduled use time of the runway will be described later.

In addition, scales -5 to 20 in the figure indicate the time required (minutes) from the present to the takeoff and landing. The aircraft symbols and reservation slots move from left to right over time. The lower right of the screen displays the delay time for the flight plan. Further, an UNDO button for returning the processing result to the previous state is displayed next to the button. 34R in the screen indicates a runway number, and KISARAZU ARRIVAL indicates a runway approach route.

Next, an allocation processing procedure in the scheduled runway time allocation unit 16 will be described.

First, in the initial stage, when the estimated arrival time or the estimated departure time is given from the landing time estimating unit 14 or the takeoff time estimating unit 15, the scheduled runway use time is allocated in order from the aircraft with the earliest scheduled takeoff and landing time. .

However, in the assignment at the initial stage, the scheduled take-off and landing time is set on the condition that (1) advance reservation of the departure aircraft and (2) advance or backward reservation beyond the controllable range of the arrival aircraft are not performed. The scheduled takeoff / landing time and the runway use start time are set to be the same (aircraft symbol and transparent reservation slot are parallel) or the difference is made as small as possible from the earliest aircraft.

Therefore, in this initial state, the aircraft symbol and the transparent reserved slot are arranged in parallel.
When the reserved slots overlap, those with the scheduled take-off and landing times are arranged in parallel with priority, and those with the scheduled take-off and landing times are arranged behind it.

The most efficient take-off and landing is when the departing aircraft and the arriving aircraft are alternately arranged. However, the reservation time is not always efficiently allocated in the initial stage. Therefore, as shown in FIG. 5, in the screen operation unit 19, the terminal controller moves the reservation slot in the arrival aircraft by operating a pointing device such as drag and drop, or the airfield controller needs the reservation slot of the departure aircraft. In accordance with the operation of the pointing device such as drag and drop, it is moved.

At this time, the screen control unit 17 outputs the change information of the scheduled runway use time to the scheduled runway use time allocation unit 16. If the change information of the scheduled runway use time indicates the reservation of (1) or (2) described above,
The screen controller 17 determines that the change of the reserved slot is invalid, and stops moving the slot.

If the change information of the scheduled runway use time is other than the reservation of the above (1) or (2), the scheduled runway use time allocation unit 16 changes the scheduled runway use time and calculates the total delay time. The recalculation is performed, and the changed scheduled runway use time information is output to the screen control unit 17 again. As a result, the reserved slot moves on the display screen in accordance with the operation of the pointing device by the controller, and the total delay time corresponding thereto is displayed.

Here, if there is an operation error or the like, or if it is desired to return to the original state at the discretion of the controller, click the UNDO button on the display screen to return to the state before the operation. To be able to do.

Next, when the reservation slot is double-clicked on the screen operation unit 19, the reservation determination information is output from the screen control unit 17 to the scheduled runway use time allocation unit 16.
In this case, when the reservation information is input, the scheduled runway time allocation unit 16 determines the reservation information of the corresponding aircraft, and outputs the reservation confirmation information to the screen control unit 17. After the reservation information is determined, the reservation change target is excluded even if a reservation change operation is performed on the screen thereafter.

When the reservation control information is input from the scheduled runway use time allocating unit 16, the screen control unit 17 paints a blank slot to indicate that the reservation has been confirmed on the display screen. When the slot in which the reservation is confirmed is double-clicked again, the reservation is released again, and the filled slot becomes blank again.

On the other hand, in the control instruction specifying unit 20, when the reservation confirmation information from the scheduled runway use time allocation unit 16 is input, in the case of an arriving aircraft, the contents of the control instruction so that the aircraft symbol and the reservation slot are parallel to each other. The timing (time) at which the control instruction is transmitted is specified. Information on these control instructions is output to the screen control unit 17 and displayed on the display screen.

Here, if the control instruction is not transmitted within a certain period of time after displaying the content of the control instruction and the timing (time) at which the control instruction is transmitted, the aircraft symbol is blinked and displayed to the controller. Call for attention.

After the departure aircraft has started to depart or the arrival aircraft has entered the final approach route, the reserved slot moves at the same time as the scheduled takeoff and landing time. That is, the reserved slots and the aircraft symbols are arranged in parallel.

FIGS. 5 to 7 show examples of specific operation methods and screen transitions. The notation in FIGS. 5 to 7 is the same as that in FIG.

FIG. 5 is an example of a screen display showing the state before the reservation change. In FIG. 5, the slot indicating the scheduled runway use time of JAS184 flight (arrival aircraft) is drag-and-dropped to the slot of JA9321 flight (departure aircraft) and JAL515 flight (departure aircraft).
6, the reallocation of the scheduled runway use time is performed as shown in FIG.

In FIG. 6, the total delay time is changed from 19 minutes 9 seconds to 10 minutes by changing the scheduled runway use time.
It has been reduced to 9 seconds (no delay time for JAS184 flight because it is advanced), indicating that this change in the scheduled runway use time is effective.

However, if it is determined that flight JAS 184 is about to arrive and it is not possible to control the arrival time ahead of schedule, then as shown in FIG.
The delay time of each ANA405 flight is reduced, while the delay time of JA9321 flight is increased. However, the total delay time is 14 minutes 9
Since it has been reduced to seconds, it can be seen that the change of the scheduled runway use time is effective.

Therefore, in the takeoff and landing control business support system having the above-described configuration, the scheduled runway use time is changed by a simple operation on the screen displaying the runway reservation status (drag and drop operation using a pointing device, etc.). Can be. At this time, the delay time of the arrival aircraft and the departure aircraft is displayed in conjunction with the operation of changing the scheduled runway use time, so that the scheduled runway use time can be efficiently changed.

Further, the control instruction contents and the control instruction transmission time for each aircraft for taking off and landing at the scheduled runway use time are specified, and displayed as information accompanying the aircraft symbol tag displayed on the screen. Since the aircraft symbol to be transmitted is identified and displayed by blinking or the like until a predetermined period elapses from the time when the instruction transmission time comes, it is possible to alert the controller.

As a result, efficient assignment of the scheduled runway use time can be performed by a simple pointing device operation on the screen typified by drag and drop. It will also identify the appropriate air traffic control messages needed to take off and land at the scheduled runway time,
By displaying the information on the screen, it becomes possible to greatly reduce the load on the control work for efficient takeoff and landing, which required advanced experience and skills. In particular, in terminal control and airfield control that required advanced experience and skills, it is possible to greatly reduce the work load for performing efficient takeoff and landing.
