Now that I have my remote compass and temp probe up and running, I've come to realize that my wind direction/velocity indicator has some significant errors. The arrow seems to agree with the conditions if I'm headed into a wind, but it almost never shows a tailwind, even if I do a 180. The main problem is the velocity indication. Again, headed into the wind it generally agrees with my TAS and GPS ground speed, but if I'm going crosswind, the number will be way off. Last night for instance I was seeing 80 knots, despite actual conditions being closer to 6 knots.
I understand this thing to simply be a difference engine, and my heading, track, TAS and GPS ground speed are all in agreement enough that I can get a general sense of winds aloft with mental calculations... How come the Dynon can't figger it out?
