Airliner engines are getting to ludicrous reliability numbers (the latest generation appears to be closing in on 10M hours between inflight shutdowns) largely through predictive maintenance performed far in advance. We’re well past ‘most pilots never see an engine failure’ and approaching ‘most airlines don’t see an engine failure’.
And there are few locations more abusive to sensors than the hot section of a turbine engine.
