Abstract

A computer-implemented method is described (19) for detecting anomalies in a transmission system (1) of an aircraft (HC<1>) equipped with a monitoring system (10,MS), which includes a number of sensors (A1-A13) coupled to the transmission system (1) and determines, for each flight of the aircraft (HC<1>) a number of respective time intervals (ΔT) and acquires through each sensor (A1-A13), for each of the time intervals (T<w>), a corresponding primary signal (s<i>) indicative of a corresponding dynamic quantity dependent on the operation of the transmission system (1) during at least part of the time interval (ΔT). For each sensor (A1-A13), the monitoring system (10,MS) determines, starting from each primary signal (s<i>) acquired through the sensor (A1-A13) during a corresponding time interval (T<w>), a corresponding set of values of at least one corresponding group of synthetic indexes (HI<1,1>-HI<1,18>). The method includes detecting (800,802,804,806) anomalies of the transmission system (1) on the basis of the groups of synthetic indexes.
