Bob, Im building an RV-7A with a FADEC engine, one B&C 60A alternator and

two PC-680 batteries. Is there any reason I cant use the Z-14 FADEC Version

and just eliminate the aux. alternator and regulator?

     What kind of engine? Do you plan a vacuum system?

Sorry I didn't give you enough info Bob.



It's a Mattituck IOF-360 with B&C starter and 60A alternator - no vacumn or mechanical gyros. It's all electric - all glass panel. It will be IFR with Garmin GMA-340 Audio Panel, GNS-480 GPS/Nav/Com, GTX-330 Xpondr (Traffic), SL-40 Com, TruTrak DigiFlight II VSGS, TruTrak ADI, GRT 4000 EIS and two Horizon  I EFISs with XM Weather. Much of this equipment will accept power from two sources. My backup to the Garmin equipment is the TruTrak ADI and the EIS 4000 option of AS and Altitude. Plus the TruTrak auto pilot. 



My plan is to use the Figure Z-14 FADEC and eliminate the aux alternator and regulator. 



Does this sound reasonable?

    Then what you REALLY need is Z13/8 with a second battery.

You have me confused Bob. I have a FADEC so why would I use the Z-13/8 - all electric airplane on a budget with P-Mags instead of the Z-14 FADEC? I just felt that with a FADEC engine with two PC-680s that I don't need a second alternator.

   Your confusing the Z-figures as illustrations of ARCHITECTURE with

   recommended combinations of hardware to end up in the finished

   design. You don't HAVE to put p-mags in for Figure Z-13/8. Figure

   Z-19 suggests an architecture for an electrically dependent engine

   having one alternator and two batteries. But again, don't focus

   on individual equipment items illustrated but the plan-a/plan-b

   operational aspects offered by the architecture. Figure Z-14 with

   a cross-feed contactor is an architecture for totally isolated,

   independent, dual electrical systems. Since you plan only one

   alternator, Z-14 is not applicable. In simplest terms, Z-19

   is an expanded version of Z-11 with a second battery added along

   with features to manage control and monitoring philosophies that

   you may find attractive. I suggested Z-13/8 because you'll have

   a vacuum pump pad with a cover plate over it. It seems a small

   cost and weight penalty to take advantage of that pad with a

   4# alternator installation. But Z-11 with dual batts, or Z-19

   is closer to what you're looking for. You can always add the /8

   feature to either system at a later date.
