power setting.

Yes, that is a nice advantage.

What powers the FADEC in the event of an electrical system failure?

No idea about the Thielert, but the FADEC controlled engine I often fly
just falls back to some default settings. I mean, it had been if it ever
had failed.

This is what happens

Larry,

A battery. Yes, in the case of the DA-42, this was implemented lousily,
as someone found out the hard way when he didn't follow the POH. The
system is being changed to prevent fools from...
Other installations are different.

In case you worry about this "single point of failure", your Lyc or
Continental has tons of them, too.

But not invovling electricity.

Any airplane I've flown that has Fadec has some sort of manual reversion.

A battery.

Are you saying the battery isn't part of the electrical system? Or
are you saying Thielert equipped aircraft carry an additional battery
dedicated to the FADEC system that is incapable of failure?

Automobile engines have been digitally controlled for two decades and
they still can overheat.

Yes, but they don't overheat because somebody set the wrong combination of
three different knobs.

What part of "so no overheating possible" didn't you understand? That
statement is simply factually incorrect.

What part of "not possible" didn't *you* understand? Frankly I don't
know abot the Thielert, but with the FADEC controlled engine *I* fly
regularly (a non-certified engine which isn't sold in the USA), I've not
been able to overheat it, and I *did* try. (Actually I've just tried to
reach the allowed limits, of course.) So yes, it's a reachable goal.

Taken literally, the statement, "no overheating possible" is indeed
incorrect. But, FADEC still gives you a protection against most of the bad
things people do to engines through poor technique.
