Aspen Avionics

I was intrigued at Oshkosh with Aspen Avionics gyro and hsi steam gauge
replacements. They have a LCD solid-state ADHRS gyro and HSI that fits into
the same slots as the steam gauges. Anybody have any experience with these
instruments? Are they shipping yet? I assume they are using these new ADHRS
and GPS on a chip. What kind of tests have these devices been through?

I was hoping someone had installed one in their plane and could comment.

It's amazing to me that they can put a ADHRS on a chip, but that's what
they're doing. I did some internet searching and pretty much found the chip
(made in South Korea as I recall), but I didn't save the link.

I would be interested to know how the FAA goes about certifying an ADHRS on
a chip. (I think I've got that acronym right.)

I think they have done that already for the G1000 and the Avidyne Entegra and
the Chelton and...

If you have an autopilot, the old attitude indicator must remain in
place to provide pitch/roll information to the autopilot. The Aspen
people are not interested (for the moment) for certifying with any
autopilot.

This information came from several owners who contacted Aspen by phone
or email and were very disappointed given the potential of the
product. It is in contradiction of what is published on their website
(FAQ).

As regards testing, TSO means next to nothing. I have a Honeywell
KFC225 autopilot which has burnt up five roll servos, one pitch servo,
failed the computer three times - all in 6 years, and they have told
me they will not be addressing this anymore. This is a TSOd product. I
don't know what the FAA requires but it obviously isn't quality or
reliability. One has to tick lots of boxes and provided they are
ticked, the product can be junk.
