<p>1. A system for controlling the flight of an aircraft (1) comprising means (7 to 10) for measuring the kinematic parameters of the flight of the aircraft, means (11) for digitally quantifying the measured parameters, means (12) for processing the quantified measurements in order to establish flight data, in particular the calculation, at the present instant (t = 0) and with respect to a representational graph, of the ordinate (yi ) of the point representing the speed vector as a function of the angle of attack (alpha ) of the aircraft, and of the abscissa (xi ) of this point as a function of the bearing of the aircraft, means (15) for producing graphic symbols corresponding to the established data and means (16) for displaying the produced graphic symbols, characterized in that the processing means (12) comprise storage circuits (13) for storing the coordinates of the points representing the speed vectors at past instants, and calculation means (14) for successive implementation of the following operations : calculation of the variation of said abscissa between the present instant (t = 0) and a cyclically preceding instant (t = -1), shifting origin of the reference axis of the abscissae of the representational graph, said graph serving the purpose of depicting the n points representing the n preceding speed vectors, said shift corresponding to said calculation of variations, and that the means (15) for generating symbols and the display means (16) have a reticle (24) comprising the last n - 1 points representing the last n - 1 speed vectors, as well as the present instant speed vector, chronologically interconnected by segments (Rvi-RVi + 1) forming a single line such that the development of the orientations of this speed vector during the most recent flight phase may be made apparent and as to permit improved piloting of the aircraft.</p> |
