| Subject: | Re: One battery/two alternators IFR z-diagram |
I'm not sure that's true. I have the same basic setup. Single battery,
two alternators and I used Z-12. The PMAGs are self-contained so you
don't have an electrically dependent ignition system. I'm using an
SB18-14 regulator for the second alternator so both can just stay on. I
have a Garmin G-5 as my backup instrument and I installed the battery on
it so in the unlikely event of a complete electrical failure I'll have
45 minutes or so to get the plane on the ground.
