A system for monitoring a measuring chain arranged to collect over time measures relating to an aircraft turbojet engine, the system comprising:
- processing means configured to build a health indicator of the measuring chain based on counting transitions between successive health words defining a validity score for corresponding successive measures;
- and
- acquisition means for acquiring over time the measures collected by the measuring chain;
- wherein the processing means is configured to build the health words by using likelihood and deviation tests between redundant paths of the measuring chain, the likelihood and deviation tests being defined according to parametering thresholds specifically selected for monitoring the measuring chain.
