Abstract
A display system for aircraft for showing the attitude, particularly the rolling and pitching position or the flight path angle, comprising a windshield projection device (HUD 'HEAD-UP DISPLAY') with devices for generating and displaying an airplane symbol, a symbol which is stabilized fixed to earth for the displaying of the position of the true horizon as well as for generating and displaying symbols for the rolling and pitching angle or of the path angle in the exterior field of view of the pilot as a function of the values measured by the corresponding instruments. In this case, a display of the attitude is generated by means of a reference symbol representing the airplane and an information symbol which changes with respect to the reference symbol in its position and shape--and is dependent on the rolling angle (.phi.) and pitching angle (.theta.) or path angle (.gamma.).
