FIELD: aviation.
SUBSTANCE: invention relates to a method and system for monitoring an aircraft engine. Generate time signal from the remaining stock of exhaust gas temperature of the aircraft engine, smooth the time signal for the construction of the first curve characterizing the residual temperature margin, identify the descending sections in the first curve, construct second continuous curve by combining descending portions, construct prediction model based on a second curve for determining the failure prediction index.
EFFECT: simple, accurate and preliminary prediction of engine failure.
