and browse (or search) for a recent thread on "electric gyros" and you will
soon be convinced that it is beneficial to get rid of the unreliable vacuum
pump in favor of a second alternator for your all-electric panel. If you
plan to fly in the clouds this should be a no-brainer decision, but the
other trade-off is the constant speed prop you'll not have.
Browse the list some more and you will realize that 18 A is probably
adequate, but redundancy requires the second alternator anyway.

Subject: 18 amps from a 914 !!!
Hi All;
I'm sorry to say that I've buried my head in the sand regarding the
relatively small amp output from the Rotax 914 I'm considering. It seems
unbelievable to me that a $15,000 turbo charged engine would have such low
amperage output...I mean geez.... the landing lights, strobe and
nav/position lights alone eat up 15 amps.
Is it true that the only option is to add a second alternator (in lieu of
vacuum so goodbye vacuum instruments)?
I'm planning my panel and seems that space in the 3/4 length panel isn't the
only limiting factor. Comments would sure be appreciated. Thanks
