1. A control device comprising:
at least one memory storing program code; and
at least one processor operable to read the program code and operate as instructed by the program code, wherein
the program code includes:
acquiring code configured to cause the at least one processor to acquire information expressing weather related to a scheduled landing location at which a landing of an aircraft is scheduled; and
control code configured to cause the at least one processor to cause an alerter to perform a behavior corresponding to the weather expressed in the acquired information, the alerter configured to perform an alert related to the landing of the aircraft,
the behavior corresponding to the weather includes starting the alert at a timing at which an alert start condition corresponding to the weather is met,
the weather includes at least one of a wind direction or a wind speed related to the scheduled landing location,
the program code further includes setting code configured to cause the at least one processor to set the alert start condition in accordance with the at least one of the wind direction or the wind speed expressed in the acquired information,
the control code is configured to cause the at least one processor to cause the alerter to start the alert at a timing at which the set alert start condition is met,
the alert start condition is a condition
that is related to a positional relationship between the scheduled landing location and the aircraft, and
that a distance between the scheduled landing location and the aircraft becomes less than or equal to a set threshold, and
the setting code is configured to cause the at least one processor to set the threshold in accordance with the wind speed related to the scheduled landing location.
