According to a process for representing information for guiding the flight of an aircraft, the airspace with at least one horizon and the precalculated flight path of the aircraft are three-dimensionally represented by means of animage display device and the surface above the horizon is subdivided into strips of different colours which extend parallel to the horizon. When the point of the precalculated flight path of the aircraft coincides with its shadow, the symbol that represents said precalculated flight path advantageously takes the position of the shadow projected on the ground. The shadow is preferably represented by a transparent design.
