Patent ID: 7433781

Claim:
A device for cartographically representing minimum vertical speeds for aircraft generating a navigation map from information in an elevation database of the terrain belonging to a particular maneuver region, comprising: Curvilinear distance map generation means for generating, in the maneuver region, multiple curvilinear distance maps listing the lengths of the shortest paths leading from the current position of the aircraft to the various points of the maneuver region while observing vertical flight profiles associated with different vertical speeds for the aircraft, means for combining, on one and the same final map, all the curvilinear distance maps obtained, selecting, for each point of the final map, the point geographically corresponding to it in the different curvilinear distance maps assigned the lowest curvilinear distance estimation, and means of displaying the selected points, showing, for each selected point, the vertical speed associated with the vertical flight profile observed by its original curvilinear distance map.
