One of the manufacturers has a panel

are the chances of getting a 337 for that if it is for backup only? I
can do partial panel, but I'd rather have the most capability that I can
get (within reasonable expense).



By installing uncertified equipment as an emergency backup, you are
essentially becoming a test pilot. How will this unit handle turbulence,
temperature and pressure changes, static charges, nearby lightning? Will
it produce emmissions that may interfere with your other radios or
navigation equipment? How much training will be required to stay
proficient in it's use? My guess is at least as much as partial panel
using a plain old turn coordinator, probably more if it is mounted outside
your normal insturment scan area. IMHO, this would not be a safety gain,
and the money would be better spent on traditional partial panel practice.
