    Abstract: A method is provided for two-dimensional graphic representation on an aircraft display screen of an image or of a symbol or of a symbology (PE) whose three-dimensional coordinates in a terrestrial reference frame are known. The graphic representation of the object or of the symbol is stretched in a vertical axis by a constant factor (α) lying between 1.0 and 1.2, the stretching having, for its neutral plane, the local horizontal geographic plane containing the aircraft. Furthermore, when the symbology is a pitch scale consisting of graduations, two successive graduations being separated by a constant angular value, the graphic representations of two successive graduations of the pitch scale are separated by a constant distance on the display screen.

    Abstract: The general field of the invention is that of the methods for graphically representing a first image from an image sensor of the outside landscape superimposed on a second image representing a synthetic image of the same outside landscape, the two images being displayed on a display screen of an onboard display system for aircraft. The first image comprises three rectangular zones of increasing transparency, each zone having a width equal to that of the first image and a determined height, the sum of the three heights being equal to the height of the first image, the first zone situated at the bottom of the image having a first constant level of transparency, the third zone situated at the top of the image having a second constant level of transparency greater than the first level of transparency, the second zone situated between the first zone and the third zone having a level of transparency that is continuously variable between the first level and the second level.

    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.
