Well, even if there is only one owner involved, I'm not going to rely on
electrically power instruments only. Never.

This amazes me. Electricity not reliable? I know this is "conventional

Glad that you never had a problem.
I have lost count of the numbers where my clubs glider's batteries
were forgotten to charge after flight or ran out of energy because
they had reached their service life...

Not to mention more than a couple of GPS failures over the years...

Of course - there have been more than a couple of mechanical (Winter)
altimeter failures, too - but at least the altimeter didn't stop
working at all but only lost precision.


It's pretty impossible to convince me of the superiority of something
that needs to be charged as long as more than one owner is involved.
This includes a backup battery. vbg
