CA 2245246

The invention relates to air navigation aid methods and discloses an air navigation assistance method using a flight management system (FMS) which dialogues with the pilot by means of a plurality of interfaces including at least one display screen. The flight management system displays on the screen a time-graduated x-axis, an altitude-graduated y-axis and, in this frame of axes, a tracing representing a theoretical trajectory of an aircraft. The flight management system makes the time axis and optionally the altitude axis run to such an extent that the origin of the axes at the display instant represents in the x-axis the time at the display instant and the y-axis the altitude of the aircraft at that instant. The pilot obtains a better appreciation of the flight time management.

L'invention concerne les procédés d'aide à la navigation aérienne. Selon l'invention, on propose un procédé d'aide à la navigation aérienne, utilisant un système de gestion de vol (FMS) qui dialogue avec le pilote par le moyen de plusieurs interfaces parmi lesquelles au moins un écran d'affichage. Le système de gestion de vol affiche sur l'écran un axe d'abscisse gradué en temps, un axe d'ordonnée gradué en altitude, et, dans ce repère d'axes, un tracé représentant une trajectoire théorique d'aéronef. Le système de gestion de vol fait défiler l'axe des temps et éventuellement des altitudes de manière que l'origine des axes à l'instant de l'affichage représente en abscisse le temps à l'instant de l'affichage et en ordonnée l'altitude de l'avion à cet instant. Le pilote obtient ainsi une meilleure appréciation de la gestion temporelle du vol.
