What type of catastrophic result?

I don't know; if you can predict a catastrophic result, you can avoid
the catastrophe.

What would you expect the software to anticipate?

I don't have specific expectations. One cannot really anticipate
everything, but the better the software, the more possibilities it is
designed to handle.

What exactly does FADEC control in a air cooled, opposed cylinder, internal
combustion airplane engine, anyway? Do you know?

That depends on the design of the FADEC, and of the engine.

Surely with your vast knowlege of writing systems like FADEC, an occurance like
an oil pump failure would be easy for you to anticipate.

I haven't written FADEC software, and every module is different,
anyway.
