[Problems to be solved by the invention]
However, the item data judged to be necessary for the flight mission or flight form is selected from many types of item data, but the flight mission or flight form in one flight is not one mission or one form. For this reason, when item data is selected in consideration of several types of flight missions and flight forms, and map data corresponding to the item data is displayed on a map, a large amount of map data is displayed at once. It becomes difficult to read and necessary map data cannot be recognized instantly.
In addition, since an electronic map display device without a selection menu displays only map data corresponding to item data determined from the beginning, a large amount of map data is displayed in a certain flight mission or flight form. Therefore, necessary map data cannot be recognized instantaneously, and in some flight missions or flight forms, necessary map data may not be displayed, and in any case, effective support cannot be obtained.
In addition, if the display scale for displaying the map is manually switched, it imposes a burden on the person who performs the switching operation, for example, the pilot, and this impedes the execution of effective flight missions and flight forms.
In addition, when the electronic map display device has a route setting function, the display scale and the map data map display are automatically switched as described above. The display scale and map data for map display may differ from those of wireless facilities, and conventional devices do not support this point. In such cases, manual switching is performed. Inevitably, this imposes a burden on a person who performs the work, for example, a pilot, and hinders the execution of effective flight missions and flight forms.
