For example, the communication terminal 40 notifies the user that the unmanned aircraft 20 has fallen by outputting a warning sound different from the earthquake tsunami warning. The warning sound may be a melody, a volume, a tone, or a length according to the failure level of the unmanned aircraft 20. Further, the communication terminal 40 notifies the user that the unmanned aircraft 20 has been dropped by displaying the received emergency alert. At this time, the communication terminal 40 may display the position information of the unmanned aircraft 20 included in the emergency alert on the map.
