<p>PROBLEM TO BE SOLVED: To three-dimensionally confirm the flying state of a flying body. SOLUTION: Three-dimensional map data is pre-stored in a map database part 11, airway position data and the other airway position data, corresponding to one's own airplane are prestored in an airway zone database part 12; and when inputting navigation data on a present position (longitude and latitude), an altitude and an airplane nose azimuth of own airplane to a navigation data input part 13, first of all, the airway position data corresponding to own airplane is read out of the airway zone database part 12 by a flying position determining part 14; a three-dimensional relative position of this airway position data and the input navigation data are determined, map data on the airway zone periphery is read out of the map database part 11 by an image-forming part 15 on the basis of this determination result; image data is formed for superimposing one's own airplane on a corresponding airway zone on a map; and this image data is displayed on a display 17 by a display control part 16.</p> |
