have adequate information about their flight systems in the POH to
inform the pilot of this possibility.


OK Neil.

You find it in the article.

My Deutsch is far too rusty to find it in the article. ;-)

POH - Under - abnormal operating procedures - 4B.7 STARTING ENGINE
WITH EXTERNAL POWER - #13 Opposite engine ..... START WITH NORMAL
PROCEDURE

That is it.

That's fine for starting the engines, but that isn't the only issue,
is it?

Is there nothing in the POH about the electrically powered items
(landing gear, FADEC, etc.)? If there is, it shouldn't require an EE
degree to realize that one should be concerned about the condition of
the batteries, charging, etc. if one has to "jump start" the engine,
or to realize that something critical is in need of attention.

Maybe I'm just an overly cautious type. ;-)

I agree that if you are flying what is basically an all electric
aircraft and you have an electrical problem on the ground that you
should take extra care before flight BUT, there should be some system
in place that doesn't allow the gear switch, landing lights or any
other electrically operated item to become an OFF switch with out
some damn significant warning.

A simple voltmeter with a "red line" should suffice, along with a caution;
"Don't take off with the needle outside the green arc". Of course, that
won't prevent someone from insisting on making a bad decision.
