a concern for my endurance scenarios, but if I want to use everything I'm going
to have on the aircraft, (continuous loads), I am in excess of 30 amps. I have
my notes which I will edit a bit and post. I would very much like some outside
review of my "plans" to see if I am on the right track with things...just
need a few days to get back into my notes. Thanks for the interest and patience!

Take a look at the documents on the website at:
http://tinyurl.com/9rt6ymn (http://tinyurl.com/9rt6ymn)
You'll find the load-analsysi work product of
several List members in Excel spread sheets.
There is also a blank planning form that I use
as the FIRST step of planning a new electrical
system.
Fill out one page for each bus . . . battery,
main, e-bus, engine, etc. List the load and
it's demands under each of the flight conditions.
I've run load analysis studies on a lot of airplanes,
one that even included pitot heat STILL came to
less than 27A for a max continuous running load.
Thanks Bob...

I have read that for planning purposes, one should reduce the alternator rating
by 20% - with that thought my 30A alternator would nominally be used as a 24A
power source for continuous duty. Yes/no?
...I will do more homework and hopefully present some better, more complete info.
Looking forward to feedback from you and the group!
Dave
