The invention relates to a method for detecting an anomaly in a system (110) of an aircraft (100), comprising: - obtaining a current series of measurements of one or more physical quantities (PT1, PT2) of the system (110), during a time period when the system (110) is in operation; - on the basis of the current series of measurements, providing, by means of an encoder-decoder (126), a current reconstructed series; and - comparing the reconstructed current series with the current series of measurements in order to obtain a current series of anomalies. The method further comprises: - computing a current distribution function of the current series of anomalies; - computing an area separating the current distribution function from a reference distribution function; and - comparing the area with a predefined threshold.
