Abstract: A method for managing a symbology in an on-board viewing system for an aircraft, the graphical representation comprising the piloting and navigation symbology overlaid on a representation of the exterior landscape, the symbology comprises a first angular attitude scale comprising a first symbol called an aircraft mockup, a second speed scale, a third altitude scale and a second symbol called the speed vector. When the angular lateral distance between the position of the first symbol and the position of the second symbol is such that the second symbol is not overlaid on the lateral scales, the various scales are represented in the nominal position; when the angular lateral distance between the position of the first symbol and the position of the second symbol is such that the second symbol is overlaid on one of the scales, the various scales move and/or their size decreases.

Abstract: The general field of the invention is that of methods of displaying an “attitude director indicator” in a head viewing system for aircraft comprising: a head support bearing a viewing device; a detection of posture; sensors for detecting the various parameters defining the attitude of the said aircraft; means for computing and graphically generating the said attitude, the set of parameters displayed being termed the “attitude director indicator”; In the method according to the invention, when the head support is oriented in a determined direction making, with the horizon line and/or with the “speed vector”, an angle greater than a first value, and/or when at least one of the attitude parameters of the aircraft becomes greater than a second value, the attitude director indicator is displayed locally in a reference frame tied to the head support and in the field of the viewing device.
