A flight management system that manages flight conditions of a plurality of flying objects and that causes the flying objects to work together in a coordinated manner to accomplish a purpose. The flight management system includes a flight management apparatus that receives instruction information, that registers a job, and that based on the job, gives a motion instruction to one or more flying objects. The flight management system includes also a job generator that generates a job, and a motion instructor that gives a motion instruction to the flying object. The job generator includes a search system that retrieves a work-performing flying object, a route setter that derives a flight route for the work-performing flying object, a time calculator that calculates a work time, and a registering system that registers a generated job.
