Abstract: The general field of the invention is that of the graphical representation of a synthetic three dimensional view of the exterior landscape in an onboard visualisation system for aircraft, said graphical representation being displayed on a visualisation screen comprising the piloting and navigation information of said aircraft superposed onto said three-dimensional synthetic representation of the exterior landscape, said synthetic representation being computed up to a first determined distance, characterised in that said three-dimensional synthetic representation is tilted at a tilt angle about an axiom positioned at the level of the terrain in a substantially horizontal plane, and substantially perpendicularly to an axis between the flight direction and the heading of the aircraft, said axis moving with the aircraft.

Abstract: The general field of the invention is that of the methods for graphic representation of the relative position of the sky and of the earth in an onboard display system for aircraft, said graphic representation being displayed on a display screen comprising piloting and navigation information superimposed on a three-dimensional synthetic representation of the outside landscape. Said graphic representation is displayed only when the attitude of the aircraft is unusual, an unusual attitude corresponding to a roll value or to a pitch value located outside of a first range of nominal values. It comprises two disc segments of identical form, that are opaque and of different colour, situated symmetrically on a circle concentric to that bearing the roll scale, the straight-line segments of the two disc segments being parallel to the line representing the zero longitudinal trim indicator, the rotation of the two disc segments being slaved to the rotation of said zero longitudinal trim indicator.
