Aerial navigation assistance system for representing e.g. terrain type obstruction zones, closest to aircraft in e.g. three-dimensional enhanced vision system type flight display device, has objects arranged together to form third object

摘要

The system has a calculating unit for calculating horizontal dimension and vertical dimension of obstruction zones (63) at risks and for calculating localization of a point (64) of the zones closest to an aircraft. An improvement unit increases display of representation of the zones with signaling objects (71, 72) of the zones, where the objects respectively indicate dimensions of the zones. The objects are arranged together to form a third object targeting the localization of the point of the zones closest to the aircraft. An independent claim is also included for a method for displaying signaling objects in three -dimensional enhanced vision system or synthetic vision system type flight display device.
