There is a pricy air driven pop out
alternator that will power the essential circuits on 210s and other aircraft it
is STC’d for (12A@28V@150kt ias,
don’t have the 12V numbers, but they are higher). Try Basic Aircraft

Good question Bulent. This is a show stopper for
me. It takes a minimum of 13 amps to drive the fuel injection and
ignition system. I agree that 1 hour endurance is a reasonable
assumption; I am using 45 minutes to allow for greater than expected
battery degredation (I wiill replace the battery yearly). I agree
that the EWP will shorten this endurance considerably. Dual
alternators would minimize this risk. Unfortunately 2 alternators just
will not fit under the cowl of my RV-4. I am considering a
snowmobile/motorcycle type PM alternator but I am a LONG ways from addressing
this feature. So I will add to Bulent's question - what will be the
current draw at 25 gallons per minute when installed in a
functioning cooling system?
