There is no change in complexity when things go wrong with FADEC.


Yes, there is, because digital systems have different failure modes
from those of analog systems, and digital failure modes are often
catastrophic failure modes.


Spoken like a sim pilot. If you had the slightest idea what the hell
you were talking about you would know that when the FADEC fails, usually
the computer goes belly up but it could be an electrical power loss, the
engine continues to run but does so at a very rich setting. If the
FADEC controls the prop then that goes to high RPM. The pilot doesn't
have to do anything except land and landing immediately isn't necessary
either. These failure modes are a requirement for certification.
