> 1. What are most folks doing in their planes?

Here's how we designed ours
2 SFS screens on the left side of the panel
Standard 6-pack all electric on the right
100 amp alternator
20 amp standby alternator (I think)
Normal battery on firewall
Emergency battery at the back with a red James Bond type switch on panel.
This switch will bypass your master switch and power one sierra screen, the
sierra EAU (Engine, Airdata Unit), the transponder, and the garmin 430 (for
COM1 and NAV1) oh! and the AHRS of course. Those who have been paying
attention lately know what that is right ?
