And on other aviation systems we do examine multiple failure modes. For example, a round going though the fuselage of an Apache, tumbling and smashing and causing spalling, thousands of simulated trials. Then coupled physics models that look at dozens of unintended interactions, avgas squirting out onto electronics, hot manifolds, etc.
There a whole field of Fault Tree Analysis that looks at how adjacent faults can propagate into unrelated components, then Event Tree Analysis to determine what will happen next. Models that assess robustness against failures even when we have no idea how the failure will occur.
Reliability of cyber physical systems is a constantly evolving field, lots of recent work on concepts like probabilistic model checking, ML for anomaly detection, resistance to cyber attacks, and so on.
