<p>The method is characterized in that there is displayed on the cathode tube of a collimator an image consisting of a circle of small size inside which there are, on one hand, a horizon line inclined to the horizontal by an angle equal to the rolling angle of the aircraft, but of opposite sign, the horizon line being remote from the center of the circle by a distance which is a function of the pitching angle in the upward direction when the aircraft is diving and in the downward direction when the aircraft is pulling the nose up, and which delimits two zones of different brightness and, on the other hand, a point representing a pole situated on the mediane of the horizon line at a distance from the latter corresponding to a pitching angle equal to 90o. The invention applies essentially to a ''head up'' type control system.</p> |
