Abstract
A method of automatically performing an engine health check for checking the health of at least one turbine engine of an aircraft. During flight, the stability of at least one monitoring parameter is verified by acquiring a measurement signal, by performing first filtering of each signal by a high-pass filter over a long first duration (TPS) and by verifying that a first amplitude (A) of the signal filtered in this way does not exceed a first threshold defined by the manufacturer, by performing second filtering of each signal by a high-pass filter over a short second duration (TPS) in parallel with said first filtering by a high-pass filter, and by verifying that a second amplitude (A) of the signal filtered in this way does not exceed a second threshold defined by the manufacturer, the second duration (TPS) being less than the first duration (TPS), and the second amplitude (A) being less than the first amplitude (A).
