PROBLEM TO BE SOLVED: To support the landing of a helicopter to a temporary taking off and landing place, by displaying the approaching direction and the landing approaching angle of the helicopter simultaneously, in a temporary landing supporting method of helicopter. SOLUTION: Around the landing point P of the temporary taking off and landing place of a helicopter, plural support lamps L1 to L4 which generate flashing lights are provided in a slender polygonal form, by providing long intervals along the longitudinal direction of the axial line C of the approaching direction H of the helicopter, while providing short intervals in the orthogonal direction. At the same time, the aspect ratio of the setting form is made in the ratio that the plural support lights are seen to form a right polygonal form when the helicopter approaches in the specific landing approaching angle, the flashing of the plural support lamps is repeated from the near side to the far side in the order of a specific time interval, and the landing of the helicopter to the temporary taking off and landing place is supported by displaying its approaching direction and the landing approaching angle simultaneously, by the flow and the form of the moving flashing light of the support lights.
