The present invention provides a method and a device for providing a pilot warning signal for a pilot of an aircraft. The method comprises the following steps: providing a first signal to indicate a pedal angle of a pedal which can be actuated by the pilot; providing a second signal which is directly dynamically dependent on the pedal angle; in each case, forming a pair of values from the first signal and the second signal at a specific time; in each case, determining an angle change of the pairs of values and an angle change of the increment of the pairs of values at two successive times; and generating the pilot warning signal when actuation of the pedal and a stimulated tumbling movement of the aircraft are ascertained and if the determined angle change of the pairs of values is greater than a first threshold value or the determined angle change of the increment of the pairs of values is greater than a second threshold value. A computer program product and a warning device are also provided.

L'invention concerne un procédé comprenant les étapes suivantes : fourniture d'un premier signal pour indiquer l'angle d'une pédale pouvant être actionnée par le pilote ; fourniture d'un deuxième signal qui dépend dynamiquement et directement de l'angle de la pédale ; formation d'une paire de valeurs à partir du premier signal et du deuxième signal, à un instant déterminé ; détermination d'une variation d'angle des paires de valeurs et d'une variation d'angle de l'incrément des paires de valeurs, à deux instants successifs ; et production du signal d'avertissement du pilote en cas de constatation de l'actionnement de la pédale et de constatation d'une oscillation en nutation de l'avion et si la variation d'angle déterminée des paires de valeurs est supérieure à une première valeur de seuil ou si la variation d'angle déterminée de l'incrément des paires de valeurs est supérieure à une deuxième valeur de seuil. L'invention concerne en outre un progiciel d'ordinateur et un dispositif d'avertissement.
