Abstract: Flight control unit 201 and flight unit 202 start flight in accordance with a flight plan. Flight history acquisition unit 103 acquires a flight history of drone 20. Flight plan acquisition unit 102 acquires a flight plan for drone 20. Inspection timing determination unit 104 calculates a difference between the acquired flight plan and the acquired flight history, and based on the difference, determines an inspection timing for drone 20. Inspection timing notification unit 105 provides notification of the determined inspection timing.

Abstract: An information apparatus includes a schedule obtainment unit that obtains flight schedule information transmitted from terminals. Allocation unit allocates an airspace and a permitted flight period to drone based on the obtained flight schedule information. If there is a predetermined commonality in the airspaces and the flight directions of multiple drones, allocation unit causes those multiple drones to share the airspace under the condition that formation flight in which distances therebetween are controlled is performed. Allocation unit determines an arrangement in which multiple drones are aligned in the order in which drones withdraw from formation flight as the arrangement of multiple drones during formation flight. Also, allocation unit determines an arrangement in which drone that does not include a formation flight function is in front and drone that includes formation flight function follows therebehind.

Abstract: A flight control apparatus includes an acquisition unit that acquires a flight plan in which first flight conditions are described, and information that indicates a time limit set with respect to a position on a path along which an air vehicle is to fly. An arrival judging unit judges, based on the acquired information, whether or not the air vehicle has arrived at the position within the time limit. A condition determination unit determines a second flight condition if it is judged that the air vehicle has not arrived at the position within the time limit. A flight control unit controls flight of the air vehicle selectively adopts a first flight control method which follows the first flight conditions or a second flight control method which follows the second flight condition based on a result obtained by the arrival judging unit.
