SASless,
as for the Airbus it's the same as with any computer; garbage in, garbarge out!
Regarding the 155 and burning engines out, that's not a fair understanding of the situation. ANY aircraft having an engine failure will use the remaining engine to try and meet the power demand at the time of failure. If the demand is too great then, for engines with a 30 second rating, the 30 second rating will be required. This will still result in Nr decay unless either the pilot intervenes (if no outer loop modes coupled) or the AP lowers the lever (if outer loop modes coupled).
With the arrial 2 series, when it was in its relative infancy, there was no cumulative time available for the 30 second rating (same on the 76 C+; same engine) and it required a module 3/4 change (equals engine change for practical purposes). It was not BURNED OUT! the engine is now in a more mature state and TM have allowed cumulative consumption of the 30 second rating.
Having seen various FDR traces, I can tell you that the AP does a much better job of handling an engine failure, than the pilots, in these sorts of incidents. But then it's easy to be an armchair critic and no criticism is intended.
Don't knock it till you've tried it!!
