FIELD: machine building.
SUBSTANCE: invention relates to a method and a system for detecting first signs of a malfunction of an aircraft engine valve comprising collecting means configured to collect measurements of the outlet pressure of said valve and control and environment data associated with said valve, processing means configured to determine a plurality of indicators of the first symptoms of a malfunction, depending on the indicated measurements of the outlet pressure and from said environment and control data, processing means configured to monitor the change in time of each indicator from said set of indicators of the first symptoms of a malfunction, and processing means configured to detect a possible deviation of at least one indicator among the set of metrics, the indicated deviation indicates the signs of a malfunction of said valve.
EFFECT: technical result of the invention is the simplification of the data of the method and the device, allowing quickly, accurately and reliably to detect the first signs of a malfunction on the valve of an aircraft engine, and also to predict anomalies.
