Several times on this newsgroup people have asked about the power
consumption of TruTrak's electronic artificial horizon (ADI), but
until now I haven't seen a definitive answer. (Apologies if I missed
it. I did do a search on the newsgroup before posting this.) I emailed
TruTrak and got the following answer:

The current draw of the ADI is around 180 milliamps. It is nearly the same for both sizes.
Please let me know if you have any further questions. Thanks!

(I had asked if there was any difference between the 2-1/4" and the
3-1/8" models.) Not bad!

My more serious concern with the ADI is how exactly the unit performs
in a glider - especially given it is *not* a normal artificial
horizon. It displays what TruTrack calls "vertical velocity enhanced
pitch". So what happens to the pitch indication when you encounter
significant change in vertical speed say in wave or even in a thermal.
Anybody have any actual experience using one of these? The pitch
indication behavior? How does the unit handle continuous high turn
rate thermalling?
