Methods for graphically managing a pitch scale displayed in an on-board viewing system for an aircraft, the viewing system comprises a graphics computer carrying out the graphical management of the symbols and a viewing screen. The symbolic representation displayed on the viewing screen includes an angular pitch scale, a symbol, referred to as the aircraft icon, that is representative of the attitude of the aircraft and a symbol, referred to as the speed vector that is representative of the direction of the speed of the aircraft. The angular distance separating the 'bars' of the scale varies so that the symbols representative of the attitude of the aircraft and of the speed vector remain constantly close to one of the two bars of the scale, even in the event of a strong crosswind. The shape of the bars is either constant or variable.

Method for graphically managing a pitch scale in an on-board viewing system for an aircraft

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.
