Abstract: In a path determining section, an optimum path is calculated based on detection/storage information of a position detector, airport surface information storage section, aircraft information storage section and knowledge information storage section according to an instruction request from a request information input section of an aircraft and is indicated by a path indicator of the aircraft. Further, a collision determining section calculates the possibility of collision on the optimum path obtained in the path determining section according to the coordinates and traveling directions of all of the aircraft based on the above detection/storage information and a warning is indicated by a warning indicator of the aircraft.

Abstract: An individual guidance system for aircraft in an approach control area under automatic dependent surveillance which, by supplying the pilot with the required flight data automatically in units of micro air spaces, permits safe and accurate flight with little scope for human error, being an individual guidance system for aircraft in an approach control area under automatic dependent surveillance wherein the air-traffic control system divides the approach control area automatically into a group of micro air spaces, and establishes flight rules within the micro air spaces in order to guide aircraft by establishing no-fly air spaces.
