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.
