Its an all electronic ADI with EFIS display. They say they are
currently engaged in certification. What do you guys think about
the prospects for use as a primary AI for a standard airplane like
my 172N ?

I emailed them, they said it would be ok after they get certified.

This seems a damm sight better than my idea to upgrade to an
electric AI. Its fully self contained, having its own inertial
and GPS guidance, and even has a mangemometer for compass heading
that is gyro stabilised.

These things work internally by having accellerometers to sense
direction change, then use the GPS to "upright" the inertial
calculation, which is one reason why it needs a built in GPS.

This means it has no rotating parts whatever, cannot spill, etc.

When Blue Mountain had an office here in COS, I got to go in and see
this thing actually work. It was real nice. But I got the impression
that they were not going to seek certification anytime soon due to the
amount of money it was going to cost them to get it certified. They
seemed happy to sell it to experimental aircraft and I believe that
there are a few planes around my area that went through the process of
getting STC'd but they are for VFR use only.
