Abstract

Système et procédé d’aide à la maintenance d’un aéronef. Le système (10) d’aide à la maintenance d’un aéronef (1) est configuré pour mettre en œuvre les étapes suivantes de façon itérative : - déterminer une densité spectrale de puissance (M(n)) de la position d’une gouverne sur une fenêtre temporelle (32) ; - lorsque la densité spectrale de puissance correspond à une amplitude d’oscillations de la gouverne franchissant à la hausse un seuil prédéterminé, mémoriser un instant de début de dépassement d’amplitude ; et - lorsque la densité spectrale de puissance correspond à une amplitude d’oscillations de la gouverne franchissant à la baisse ce seuil prédéterminé : . déterminer un intervalle de temps (ΔT) entre l’instant de début de dépassement d’amplitude et un instant de fin de dépassement d’amplitude, pendant lequel l’amplitude d’oscillations de la gouverne est restée supérieure au seuil prédéterminé ; et . déterminer un indicateur (IND) représentatif de l’énergie correspondant à ces oscillations pendant ledit intervalle de temps (ΔT). Figure pour l’abrégé : Fig. 3
