Not for nothing, just my 2 cents. Built a Lancair Legacy panel from scratch ( see attached ) Had a high dollar EFIS, wouldn't TRUST it for the world. It had my aircraft down more times then I like to remember, how about the unit 4 months at the factory for repair one time, $1000 repair Bill, got it back still had the same problems. You almost want to visit the factory with an AR-15!!! For the type of flying most of us do, nothing is going to beat a 6 pack with HSI, and a unit like a Certified Gamin W530. Yes my panel was pretty . . . if you don't mind a LOT of DOWN TIME, and restricted to VFR. I wouldn't have another uncertified, NON TSO, unit in my Panel.

In my "Glazed and Confused" presentation on "Glass Cockpits" I say that
flying an aircraft with a non-certified, non TSO'ed glass standby
(Dynon et al) is like jumping out of an airplane with only your main
parachute and your standby plan is the fact you are wearing real soft
socks.
Jeff referred to one of my earlier posts where I said.
"Regarding the question of backup systems, the more isolated your
backup is from your primary, the less likely they will both be killed
by the same event. If you wanted to guard against one of the windows in
your house from being shattered by a miscreant juvenile with a penchant
for throwing rocks you probably wouldn't put a second pane of glass
behind the first as a single litho-projectile would destroy both.
A spinning mass gyro is still the best standby for your EFIS system.
They operate on different physics than the MEMS AHRS, they can, with
internal or external battery, be independent of ship's power,
they
are familiar to all pilots and they are a cheap way to have TSO'ed
gyro instrumentation."
