Method and system for enhanced 3d awareness of the environment linked to the ground around an aircraft and anticipation of the potential environmental threats

A method for enhanced three-dimensional awareness of the environment linked to the ground around an aircraft and anticipation of the potential threats of said environment;

• the method for enhanced 3D awareness of the environment and anticipation of the potential environmental threats being implemented by a system for enhanced 3D awareness of the environment around the aircraft and of potential environmental threats comprising:
• an electronic enhanced three-dimensional environment awareness and piloting assistance computer;
• and
• an obstruction database configured to provide the electronic environment awareness computer with data modelling a set of obstruction objects likely to be environmental threats for the aircraft;
• and
• a primary flight display PFD, included in a synthetic vision system SVS or derivative, and configured to conformally display, in the terrain representation, a flight path vector symbol;
• the method for enhanced three-dimensional awareness of the environment and anticipation of potential environmental threats comprising:
• a first step of calculation of a panoramic curve representing the trend of a safe minimum slope for crossing obstacles as a function of the azimuth angle of the aircraft in its local horizontal plane of lateral movement;
• and
• a second step, consecutive and executed on command, of display of the panoramic curve of safe minimum slope and of any piloting assistance information.
