Threat source such as radar, is one of the most important factors which must be considered in route planning. Some threat sources generate so large threat area that the whole planning field is covered by it. In these areas, some threat areas can be observed by threat source, called visible area while others can not be observed due to the overlapping of terrain, called invisible area. In order to lessen the route planning cost, invisible area should be utilized as more as possible. In this paper a fast route planning approach which uses invisible area and the high maneuverability of aircraft is presented. After the comparison of theoretical analysis with experimental results, it is concluded that our approach needs much less planning time than the traditional algorithm.
