As a former jet jockey, myself, I prefer simplicity and fewer
switches.Â* And, whereas one big battery would be nice (forgetting
single point failures), space quickly becomes an issue.Â* It's much

finding a place for a big one.Â* One of my friends removed the nose
ballast from his glider and replaced it with an SLA battery.Â* A much
better use of lead, don'tcha think?

look in the cockpit

There's a lot to be said for reducing component count.

Yes, there is a definite charm to single point-of-failure systems.

But charm don't count when the failure occurs and you are out of backups and ideas.




I got an idea! How about you keep flying the A/C? Do you fly a glider
that crashes if you lose the panel? In 40 years of flying with a
single battery for the avionics, I've never lost the panel. Absolutely
could happen. Not catastrophic if it does.

The reality is all the solutions proposed have single points of failure.
If you can't handle an occasional failure, maybe find a different hobby?
