I have a TruTrak Digitrak, wing leveler (not altitude) that is connected to the Garmin 296. The 296 is also providing data to the Dynon D100.
I had noticed the HSI taking too much time to "recover" on turns and also the Digitrak, while doing a wonderful job of holding heading, wasn't tracking the 296 when it had an active flight plan.
I doublechecked all the settings and found only one "mistake."
While the TruTrak instructions says the NMEA In/NMEA Out on Com1 can either be Fast or Normal, my pal Mike Hilger says it needs to be on normal because fast output drops serial sentences the A/P needs.
I also made sure the subcategories were set to "off" as the instructions require.
Also, doublechecked the AP to make sure the baud rate was 4800.
As before, the AP display said "OFF," which indicates the presence of good GPS data. And the Dynon was displaying good GPS data.
As I taxiied to the runup area, I noticed the "OFF" had changed to ---, indicating no GPS data, but upon takeoff, it was again showing "OFF" and everything was normal.
The Dynon data was rock solid. With the change, the HSI display had settled down nicely and was working great. Some additional information also appeared that hadn't appeared before (note to self: Read the instructions in the Dynon manual and find out what that information is)
I guess in the big scheme of things, it's not a big deal. It's not like I really need the function too much. I can just push it "on" and let track heading if there's something I need to concern myself with inside the cabin. But I kinda want a "hey, that's cool" moment.
Any ideas?
