Claim 4:
5. A non-transitory computer-readable storage medium encoded with computer-readable program code having computer-readable instructions which, when executed by a computer system including at least one processor, causes the computer system to function as a flight path calculation system which executes a method comprising:
storing, by at least one processor, three-dimensional map data in horizontal and height directions at which no ground objects exist and where an uninhabited aircraft is allowed to fly;
acquiring, by the at least one processor, a current position of the uninhabited aircraft;
acquiring, by the at least one processor, a destination of the uninhabited aircraft;
calculating, by the at least one processor, a path which allows for flight in the map data from the current position to the destination;
acquiring, by the at least one processor, a warning area determined from wind condition data that flight should be avoided;
recalculating, by the at least one processor, the path avoiding the warning area when the path previously calculated is a path which passes through the warning area;
storing, by the at least one processor, an emergency landing allowable area at which the uninhabited aircraft can make an emergency landing;
giving, by the at least one processor, an emergency landing instruction to the uninhabited aircraft in flight to make an emergency landing on the emergency landing allowable area;
recalculating, by the at least one processor, the path from the current position to the emergency landing area when the emergency landing instruction is given;
storing, by the at least one processor, transport item urgency data by which the transport item of the uninhabited aircraft can be distinguished as to whether the transport item is an urgent transport item; and
judging, by the at least one processor, whether the transport item urgency data related to the uninhabited aircraft which is made to make the emergency landing indicates the transport item is of high urgency;
wherein the at least one processor is configured such that, when the transport item is judged as being of high urgency, the emergency landing instruction is not given and flight of the uninhabited aircraft is continued.
