摘要：The object of this paper is a method that allows to determine the criticality of a system. As a case study, it is considered a Variable Pitch Propeller (VPP) Plant: at first it is studied to understand its characteristics and operating logics and, subsequently, four possible Operating Modes were identified. For each Operating Mode a fault tree is modelled in TARAS, a software that allows calculating the MTBF (Mean Time Between Failures) of the plant. Subsequently, the results are validated using a block diagram. Finally, a FMECA (Failure Mode, Effects, and Criticality Analysis) is carried out: it includes both an analysis aimed at highlighting which are the possible failure modes and their consequences on the operation of the VPP Plant and a criticality analysis aimed at identifying which items are more critical than others for the specific Operating Mode and which Operating Mode is more critical than other.
