Display system, aircraft and display method for displaying a virtual point of impact on a helmet display

A display system configured to display a virtual point of impact on a helmet display, the helmet display being fitted to a helmet worn by an operator of an aircraft, the virtual point of impact designating a predicted real area of impact between an element projected by at least one sighting member of the aircraft and an obstacle of a surrounding environment, the at least one sighting member being configured to be maneuverable by the operator, the display system comprising at least one identification assembly comprising:

• a measuring member measuring a distance D between the at least one sighting member and the obstacle;
• a first positioning device capable of determining a position and an orientation of the at least one sighting member with respect to the aircraft;
• a measuring means measuring at least one kinetic parameter related to a movement of the aircraft with respect to the obstacle;
• a measuring system measuring at least one external parameter related to a speed and orientation of the wind;
• a first controller configured to determine a trajectory of the projected element as a function of at least one type of element used, the kinetic parameter, the external parameter, the distance D as well as the position and orientation of the at least one sighting member with respect to the aircraft;
• a second positioning device capable of determining a position and an orientation of the helmet with respect to the aircraft;
• and
• a second controller configured to identify, on the helmet display, the position of the virtual point of impact as a function of the trajectory of the element and of the position and orientation of the helmet with respect to the aircraft;
• wherein the second positioning device comprises first sensors arranged in an interior volume located inside a cabin of the aircraft, and second sensors arranged in at least one exterior volume located exterior to the cabin, the cabin being located outside a cockpit of the aircraft, the at least one exterior volume being separated from the interior volume by at least one opening of the cabin communicating with the surrounding environment.
