FADEC = complex

Tell us, how a oil pump failure is made worse, with FADEC?

The software may not be designed to anticipate and react to an
oil-pump failure. The failure may cause the software to follow and
unexpected and unpredicted path, or it may cause a fault in the
software; both can produce catastrophic results.

The error may be one of system design (inadequate specifications), or
one of coding (careless writing or testing of code).

Explain how FADEC could be made to take into account a oil
pump failure, or how not having FADEC makes the oil pump failure
any better of a situation.

I'm not an engine specialist, so I'm not sure how best to deal with an
oil-pump failure.

Mxsmanic,

I'm not an engine specialist,


Oh, really?

Damn! You had *me* fooled!

What type of catastrophic result? What would you expect the software to
anticipate? What type of path might it follow?

What exactly does FADEC control in a air cooled, opposed cylinder, internal
combustion airplane engine, anyway? Do you know?

The error may be one of system design (inadequate specifications), or
one of coding (careless writing or testing of code).

Surely with your vast knowlege of writing systems like FADEC, an occurance like
an oil pump failure would be easy for you to anticipate. What would you have
the FADEC system do, if it were you?

That is the first accurate and truthful statement I have ever seen you write in
this forum. Congratulations.

I don't know; if you can predict a catastrophic result, you can avoid
the catastrophe.

I don't have specific expectations. One cannot really anticipate
everything, but the better the software, the more possibilities it is
designed to handle.

That depends on the design of the FADEC, and of the engine.

I haven't written FADEC software, and every module is different,
anyway.
