Abstract: Provided are a control device and a control method by which an airplane can maintain flight while maintaining a high level of safety, even if there is a conceivable abnormal event such as a communication failure or an obstacle. This control device is for an airplane, the control device being characterized by: comprising a setting unit that sets a main flight route, which is a normal flight route, and at least one secondary flight route, for each of a plurality of airplanes, and a management unit that prevents interference between a given main flight route and a given secondary flight route, and a main flight route and secondary flight route of another airplane; obtaining information about an airplane or the surrounding airspace; and when the information matches a preset prescribed condition, permitting the airplane to operate using the secondary flight route.

Abstract: An operation management system is capable of safely and space-efficiently optimizing an operation path in accordance with various events. The operation management system manages a flight of an airframe such as a vertical take-off and landing plane. The system includes a 4D path planning unit that plans a 4D path, of the airframe, represented as a series of planned passing positions and time of the airframe. The system has an occupied space design unit for designing, as occupied spaces of the airframe prohibiting entry of other airframes, a movable occupied space that includes the airframe and that moves together with a mobile body and a fixed occupied space that includes the movable occupied space and that is along the 4D path. The 4D path planning unit re-plans the 4D path on the basis of a positional relationship between the movable and fixed occupied spaces during the flight of the airframe.
