We have two new RV-12iS aircraft coming soon to our flying club. I've never flown one, but as the Ops Officer I need to understand them.
I believe there's a switch on the upper console marked "EMS Backup Battery". As far as I can tell, there's no backup battery; this switch allows the main aircraft battery to power the ignition in case both generators fail. Do I have that right?
If Generator A fails, Generator B powers the EMS but the rest of the airplane is running off the main battery. If the battery voltage drops too low to run the fuel pumps, the engine stops. Correct?
The POH advises to turn off non-essential electrical equipment with a generator failure. I wonder if that ought to include one of the fuel pumps.
If both generators fail, I assume the engine stops until you flip on the EMS Backup Battery switch and then restart the engine.
These will each have a G3X display, and I understand there's an actual backup battery for that. But if aircraft power is lost, the fuel pumps stop and the engine stops. So this backup battery is just to keep the EFIS running during the final glide? This makes me wonder whether there's something I don't understand.
Can someone who knows this system confirm that I'm on the right track?
