Abstract
The invention concerns a method for monitoring the operating state of a system for positioning variable-geometry members () of a turbomachine (), the members () being configured to travel over an operating area comprising a first position Pand a second position P, the method comprising the steps of: —(E) determining a first pivoting speed Vfrom the first position Pto the second position P; —(E) determining a second pivoting speed from the second position Pto the first position P; and—(E) determining an anomaly in the operation of the system for positioning the members () if the first speed Vis lower than a first determined speed threshold and/or if the second speed Vis lower than a second determined speed threshold.
