Follow-up: yesterday I did my first x/c with the Oudie/SYM + SN10. (An

SeeYou Mobile is *much* happier with the air data from the SN10. The
combination worked great. I would go so far as to say that SYM's
thermal assistant is next to useless without the air data (which I
would expect), while very effective with.

But is it the airdata that made it better or the external GPS position
source?

The HP310 internal GPS makes the LK8000 thermal assistant useless but
it may well work better with an external GPS. It seems to work quite
quite well in replay mode using 2 second flight logs from the 302.
Also with internal GPS the 310/LK8000 circling wind estimates are
sometimes hazardously misleading.

I don't know anything about the charactersitics of the Oudie internal
GPS but I doubt it was optimized for aviation. Was it?
