INFORMATION PROCESSING APPARATUS

A flight information acquisition unit periodically acquires flight information (information indicating flight status, including the position and flight direction of the host aerial vehicle) of a drone. A flight irregularity determination unit determines, based on the acquired flight information, whether or not a drone belonging to a group under control of this device is flying with deviation from a flight plan. Based on the flight plans of drones belonging to another group, first collision specification unit specifies a drone at risk of collision with a drone that is performing irregular flight. When the flight status of a drone that is performing irregular flight is acquired, a flight irregularity notification unit gives notification of that flight status to a server associated with a drone specified by a first collision specification unit.
