Abstract
The field of the invention is that of methods of synthesizing cartographic images presented on display devices. This method is applied more specifically to visual flight on rotary-wing aircraft. The method according to the invention is used to present the useful aeronautical map information superimposed on a conventional altimetric presentation of the terrain being flown over, while retaining a legibility that is acceptable to the user. Flight safety is thus significantly reinforced. To obtain an enhanced legibility, the method displays only the aeronautical zones included in an altitude band corresponding to the flight phase of the aircraft and dependent on the geographic location and the vertical position of the aircraft. The method is used to display the cartographic representation either on a single window comprising a plan view of the terrain being flown over, or on two windows respectively representing a plan view and a cross-sectional view of the terrain being flown over.
