DA 42 accident

The problem is not FADEC. It is pilot error -- taking off with a known
electrical problem in an airplane dependent on electricity to fly,
coupled with a poor understanding of how an alternator works.

Maybe the problem in =this= flight was pilot error, inasmuch as the
takeoff would be ill-advised under the circumstances. However, the
accident does illustrate a weak point of the system. There are other
ways to trigger that weak point.

Really? Name one.


I don't know the system, so I can't second guess the engineers
intellegently about it. However, it does seem to be a serious
oversight that the engines themselves can't supply their own juice.

They do -- with an alternator on each engine. There is also a
generator. How predictable is the failure of two alternators, the
batteries, etc?
