PROBLEM TO BE SOLVED: To suitably set a via-point on a grid-like flight route.SOLUTION: A control section 18 of an aircraft 10 is configured to: divide map data 155 including at least a destination point P, and arrival point Pinto a plurality of grid-like cells C in an in-horizontal plane; set a cell route Rmade up of a plurality of continuous cells C from the destination point Pto the arrival point Pon the map data 155 subjected to the grid-like division; calculate a flex angle θof the cell route Rin a cell Con the cell route R; and, when the flex angle θin the cell Csatisfies a relation of θ≥θ<θwith respect to a flex angle θ, θin two cells C, Cadjacent in front of and at the back of the cell Con the cell route R, set the cell Cas a via-point P.SELECTED DRAWING: Figure 2 |
