FIELD: engines and pumps.
SUBSTANCE: invention covers method and system for aircraft engine flaw detection. Proposed system comprises means 5 to define pattern of behaviour of aircraft engine control means 21 using time-base regression to simulate behaviour of said means 21 depending upon set of data related to said control means and including past measurements of behaviour. It includes also measurements of control means states and instructions and means 5 for continuous recalculation of said behaviour pattern for every new data set. Besides, said means 5 effects control over statistic variation of said pattern to reveal control means behavior pattern abnormality that reflects that of engine 1.
EFFECT: optimised computation time.
