The device (1) comprises a first means (3) for measuring the effective value of the velocity vector of the aircraft, a computing unit (4) which determines a display value automatically and repetitively and which comprises a filtering means (6) which filters the value measured by the first means (3) so as to form a first term, a display unit (7) for presenting on a screen (2) a characteristic sign illustrating the velocity vector whose position on the screen (2) is representative of the display value, and a second means (9) for determining the derivative of a velocity vector controlled by an aircraft pilot. The computing unit (4) further comprises a computing means (10) which determines a second term from the derivative of the controlled velocity vector and a summator (12) which sums the first and second terms so as to form the display value.

Le dispositif (1) comporte un premier moyen (3) pour mesurer la valeur effective du vecteur vitesse de l'aéronef, une unité de calcul (4) qui détermine de façon automatique et répétitive une valeur d'affichage et qui comprend un moyen de filtrage (6) filtrant la valeur mesurée par le premier moyen (3) pour former un premier terme, une unité d'affichage (7) pour présenter sur un écran (2) un signe caractéristique illustrant le vecteur vitesse, dont la position sur l'écran (2) est représentative de la valeur d'affichage, et un second moyen (9) pour déterminer la dérivée d'un vecteur vitesse commandé par un pilote de l'aéronef. L'unité de calcul (4) comprend de plus un moyen de calcul (10) qui détermine un second terme à partir de la dérivée du vecteur vitesse commandé et un sommateur (12) qui fait la somme des premier et second termes pour former la valeur d'affichage.
