FIELD: monitoring systems.
SUBSTANCE: invention relates to a method for monitoring the degradation of device onboard an aircraft during its operation. To this end, a computer determines the degree of the degradation of the onboard device based on an abnormality score determined by counting abnormality of occurrences of anomalies detected by a device of the control system during its operation in a certain manner, compare the abnormality score with a decision threshold, transmitting an alarm signal in case the threshold is achieved or exceeded.
EFFECT: automatic alarm is triggered depending on its likelihood.
