FLIGHT PATH SEARCH DEVICE AND FLIGHT PATH SEARCH PROGRAM

There is provided a flight path search device. A storage unit (15) of an aircraft (10) stores map data (155) and enemy force range information. A control unit (18) divides the map data (155) into cells (C), calculates a score (P) about the attack avoidance degree of each cell (C), and calculates a destination point cell (Cg). A cell (C) optimal to move to from the current location cell (Cp) when moving to the destination point cell (Cg) is searched from adjacent cells (C), based on the score (P. The current location cell (Cp) is updated to the optimal cell (C) if it disagrees with the destination point cell (Cg). The control unit (18) sets a hover area (HA) as the initial current location cell (Cp). The process is repeated until the optimal cell (C) agrees with the current destination point cell (Cg).
