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

Yes, but when you take off without any charge in your back-up battery,
it is the idiot at the stick bypassing the reversion that is the
problem.


It's irrelevant when you're talking design flaw. On that occasion it was
the idiot, but thre's a thousand ways the fadec can be robbed of sparks.
Every airplane I've flown with a fadec, ECU, EEC or whatever, has had soome
sort of limp home capability. This one does not. No electrics, no power.
I've had two Fadec malfunctions in the last four months whihc required a
disconnect and reversion to manual FCU. No big deal. 90 seconds n the
checklist and we were back to bitching about how hard our lives were

Drain the coolant and go flying. Tell me how long the FADEC
prevents the engine from overheating.

Yawn. Dry the oil and go flying.

So, you finally admit that the FADEC can't prevent overheating.

FADEC can't prevent to become a moron, either.

True, but that wasn't the original claim.

No, I never claimed that.

Yes, this may be the case, however the TBR has to get closer to 4,000

twice as long as similar size gas engines, so with Lycs and Contis
lasting 2,000 hours fairly routinely, the Thielert needs to at least
double that ... unless the replacement cost is equivalent to an
overhaul of a Lyc or Conti.

Of curse I did completely misunderstand you. No, please don't explain.
It gets boring.

Yes, what part of "unless the replacement cost is equivalent to an
overhaul of a Lyc or Conti" wasn't clear?

Yup, gotta pay for the new improved NAS. JetA power GA aircraft are
going to pay more taxes per gallon than the 100LL drivers, so UnkaSam
wants more JetA sales...

The salespeople at AOPA were really cagey WRT the Diesel 172. As best
several of us can figure, this is for the overseas market.

The salesperson did mention, for example, that 100LL was not to be found
in South Africa. I've no idea whether or not this is true, but it seems
to indicate the target market at which this is aimed.

I think those Theilberts are throw away at 1800 hours or something...

You think wrongly. It's 2400.

Ok, so throw away the engine at 2400 hours...

Re ringing and doing valves are things that an air cooled engine may need often, but a diesel will probably not need
until it is replaced.

So the diesel is liquid cooled?

It's liquid cooled, so no discussion about shock cooling anymore.
It's fully FADEC controlled, so no overheating possible.
It's geared, so a prop strike doesn't affect the engine.
It's fully FADEC controlled, so always best prop pitch to the chosen power setting.
and and and... in short, everything I would expect from a modern engine.

Blueskies,

Yup. You were probably trying to make a point by mentioning it. What is
it?

Ain't that great? Power by the hour. You know in advance what it
will cost you to run that engine 2400 hours. No surprise midtime
overhauls. If it doesn't make TBR, Thielert will prorate it on the
new engine.

That is great as long as the cost per hour is competitive.

I pointed you to the numbers. But I understand that you're too lazy to
do the math but want to argue just for the sake of arguing.

Well I missed it. How much is the replacment and how much will it cost?

Ah, I finally understand. I've always thought you were insuinating
something by insisting that the Theilert ist only a good deal provided
it is a good deal and repeating that statement over and over. But I
finally understand that you didn't insuinate anything. You just meant
what you wrote: It's only a good deal if it's a good deal.

I don't know how you call such a statement in English, but in German I
call it a "Null-Aussage", a zero-statement. It's only a good deal if
it's a good deal... geezz. Sorry for searching for a message in your
statement.
