Description of the Related Art Generally, when changing the flight route of an aircraft, it is necessary to perform a simulation based on the changed route information in advance to check whether there is a collision with another aircraft. Usually, a point called FIX is defined at predetermined intervals in the flight path of an aircraft, and when an aircraft intersects with the flight path of another aircraft, the air path is set so as to always intersect at this FIX point.

However, in the future, there is a high possibility that a flight route that intersects other than the above-mentioned FIX point will be set, and there is a possibility that detection of a collision in such an air route becomes extremely difficult. Further, in the above-described air route, it is necessary to detect a collision with another aircraft in all the air routes, and the operation requires much time and labor as compared with the conventional operation.

There is a point above the airport where landing aircraft must pass. The aircraft to land must pass through this point after a predetermined time and a predetermined distance after the aircraft to land immediately before passing through this point to avoid collision at landing. There is a provision that must be. Therefore, when setting the air route of the aircraft, it is necessary to adjust the time of the passing point provided above the airport.

Based on the route information of each aircraft stored in the air route information storage unit 10, a time at which the vehicle passes a specific point, here, a point set above the airport, is calculated. Subsequently, the second detection unit 16 refers to the passage time calculated by the time calculation unit 15, and calculates the route information of the aircraft in which the interval between the passage times is shorter than the reference interval. , And outputs the information to the change unit 14.
The changing unit 14 changes one or both of the detected route information of the two aircraft in a direction in which the interval between the passing times is longer than the reference interval, and stores the changed route information in the registration unit. 11 is reflected in the registration data. More preferably, the changing unit 14 reduces the number of aircraft that change the route information as much as possible, taking into account not only the two detected aircrafts, but also the passing times of the aircraft ahead and behind the aircraft. It is preferable to change the route information of each aircraft during the period.
