PROBLEM TO BE SOLVED: To make a pilot grasp visible relations between an own aircraft and an object objectively and precisely and select an appropriate attack position.SOLUTION: In a visible relations derivation method, as to two arbitrary target points on any line extended on a horizontal plane from an object, distances between the two target points and the object, and an angle formed with a tie line of an altitude point corresponding to altitude of the two target points and the object, and the horizontal plane is derived(S2), and whether the altitude point of a target point having a long distance with the object becomes visible state for the object by a positional relation with the altitude point of a target point having a short distance with the object(S4) based on the distance and the angle with the object of two target points. |
