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
