Putting the Duke accident aside....my thoughts and prayers are with the
family and friends.

So, if I understand it correctly, the EPS V8, which is electrically
dependent, only has one alternator?  All that technology, and only one
alternator?  I don't get it.........  The people that are putting these
in Lancairs, is this the configuration you are installing them with?
Being a EE, and with all the technology out there, especially on an
electrically dependant engine, there is NO way I'd even sit in it
without dual alt/dual bat system.

To Shannon and other members of the list,

The EPS V8 comes standard with one large capacity alternator.  All customers
are strongly encouraged to install the dual buss system that incorporates
two large capacity batteries and dual redundant switchable busses.  I am
unaware of any customer who has not installed a dual buss system in their
planes.  In the event of an alternator failure, the dual bus will allow
continued flight for up to two hours on the battery capacity of the two
busses, more than enough time to undertake a precautionary landing for
alternator repairs.  Many customers feel like you and choose to install a
second optional alternator when their planes are all electric.  The Duke was
a one of a kind installation, still under development, with further
engineering and flight testing yet to be done to work out the details of the
electrical and other systems.  EPS had no idea the plane would be flown so
"aggressively" in its early hours of life.  No amount of engineering will
overcome a pilot's choice to fly without fuel or without adequate
electricity in their systems.
