PROBLEM TO BE SOLVED: To solve a problem that although an uninhabited fixed-wing aircraft is transferred to a phase of glide landing after passing through a landing intrusion point, it extremely excessively passing a landing point on a flight plan by influence of tail wind. SOLUTION: When it is calculated that a presumption landing point excessively passes a set landing point, landing intrusion is performed again. At the execution, the landing intrusion point is moved in a direction left from a landing point by an excessive degree and also cope with tail wind. Further, by regulating behavior of re-approach, landing at a narrow space area is attained. Further, at the intrusion to the landing intrusion point having a passing determination condition for linearly intruding it to the landing point, linear intrusion is attained by performing flight along a circumference of a circle in which a line connecting the landing intrusion point and the landing point becomes a tangent.
