Right.


MX has informed us of the risks associated with these electronic engine
management systems on several ocassions.


In particular regard to this installation? I have no problem with computer
governed engines, once tey aren't reliant on th ecomputer to run which
isn't the case with any other engine I know of.

I see your point and I think it's a good one. As I said before, I
smell the rat of marketing...

That doesn't address anything.

Bertie,

You're almost as funny as MX with your taking things out of context at
will. He's better at it, though.

Hmmm, could be. Lots of turboprops have fadecs now. The latest Pratts, I
beleive. I was having this ocnverstation with an FO who had come off a
Dash-8 and he told me the latest version of it ( Q400 or something?) had
them. I said "yeah, but they don't have this problem with power, though,
surely" and he told me that they probably did since power was definitely
required to run the fadec. They tell us very little about the innnards
of these fuel units, but I cant see them icencing an airliner without
enough system seperation to ensure that one failure doesn't kill two
engines at once.
I can't see the point of having a Twin star when it can effectively be a
single engine airplane if the lights go out.
i know someone who bought one on behalf of his club and he agreed with
me that it was a feature of the design, but insisted that it will NEVER
be a problem as long as you follow the POH. If anyone here besides
Anthony, met this guy RL, No more confirmation would be necessary that
this was a baaaaad idea.

At least in the Meridian they have a manual override lever which is
directly connected to the FCU via cable linkage. I know it's not
FADEC, but maybe they have a similar emergency mode in the -8.

The specific problem the crash flight had (draining the battery and
killing the FADECs) was corrected via AD requiring backup battery to
the FADEC in case you screw up the ships battery. Each engine has a
FADEC, each engine has it's own alternator and backup FADEC battery.
For that specific problem they've now put in redundancy.

But the fadec still relies on electrics to make the engine run.


I knew about the AD, BTW.

You keep want to blame Marketing. Sure they may have said we need to
have an easy to use FADEC system but it was the engineers that decided
not to have the limp home mode.

Gig,

Sure they may have said we need to

not to have the limp home mode.


In a way, they do (if not in the way it used to be installed in the
DA42): the emergency battery. I guess what I'm trying to say is: This
engine is different than the old Lycs and TCMs. Doesn't mean it's worse.
Just different.
