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

Abstract: A flight control apparatus includes a detection unit that detects within a predetermined range of an air vehicle another air vehicle. A specifying unit specifies a type of the detected other air vehicle. A determining unit determines a possibility that the air vehicle and the other air vehicle will collide, based on an attribute relating to movement of the other air vehicle. When it is determined that a possibility of collision exists, a flight control unit controls the flight of the air vehicle according to the specified type of the other air vehicle to avoid collision with the other air vehicle.

Abstract: Flight cessation detection unit detects that drone has ceased flying at an unexpected site. Situation information acquisition unit acquires, as situation information indicating a situation related to retrieval of the drone, information on weather in an area in which the drone has flown. Retrieval procedure determination unit determines a retrieval procedure for the drone based on a situation indicated by the acquired situation information. Retrieval procedure determination unit, upon detecting a time period having specific weather based on the acquired information on weather, determines a retrieval procedure in which the time period is designated as a retrieval time.

Abstract: The location detection unit detects a destination location for delivery of an item by a drone. The release determination unit determines whether the drone transporting the item can release and place the item at the destination. Upon determination that the release and placement is not possible, a standby airspace determination unit determines a standby airspace within which the drone waits. The wait-time determination unit determines a wait-time for the drone in the determined standby airspace. The wait-time determination unit determines a wait-time by which the drone can arrive at a next destination by a scheduled arrival time following departure of the drone departs after standby. The standby instruction unit issues to the drone an instruction related to the standby.

Abstract: Allocation result accumulation unit accumulates allocation results of each business operator that requests allocation of flight airspace of drone. Allocation result accumulation unit accumulates, as the allocation results, an allocated airspace amount represented by the size of allocated flight airspace and the period in which flight in the flight airspace is permitted. When allocation requests are received from multiple business operators, flight airspace allocation unit allocates flight airspace by giving priority to a high priority business operator according to the allocation results accumulated in allocation result accumulation unit with respect to each business operator. Flight airspace allocation unit allocates the flight airspace by assigning a higher priority to a business operator for which the allocated airspace amount that has been accumulated is small.

Abstract: A flight control apparatus that enables a flying object to safely pass another flying object includes a detection unit configured to detect, in a predetermined range from a flying object, another flying object. A specifying unit is configured to specify a moving direction of the detected other flying object. A judging unit is configured to judge, based on the specified moving direction, whether or not passing is possible. A determination unit is configured to determine, based on a relationship between the flying object and the other flying object, content of a passing operation to be performed with respect to the other flying object. A flight control unit is configured to, if it is judged that passing is possible, control flight of the flying object and perform the passing operation according to the determined content.

Abstract: Flight type determination unit determines a flight type of drone on the basis of parameters obtained by flight schedule obtainment unit. The flight type includes a travel type, which uses a destination as a parameter, a touring type, which uses a range in space (a touring range) as a parameter, and a hovering type, which uses a position in space (a hovering position) as a parameter. Allocation rule storage unit stores allocation rules for flight airspace corresponding to each of the plurality of flight types. Flight airspace allocation unit allocates flight airspace to drone on the basis of allocation rules corresponding to the flight type of that drone as indicated by the parameters obtained for that drone.

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.
