  • Publication number: 20180286256
    Abstract: A flight controlling apparatus includes an information acquiring unit, a point searching unit, a determining unit, and a route changing unit. The information acquiring unit acquires location information of a factor on a ground that possibly influences safety of an aircraft in landing. The point searching unit searches for one or more landing candidate points to prepare for an expected abnormality in the aircraft in flight, on the basis of the location information. The determining unit determines whether the one or more landing candidate points are selected to prepare for the expected abnormality. The route changing unit changes a flight route of the aircraft to cause the one or more landing candidate points to be obtained to prepare for the expected abnormality in a case where the determining unit determines that no landing candidate point is selected to prepare for the expected abnormality.
