RICHAWK,
I have a Garmin 430W/GI106A in my panel with Skyview and the ARINC module also. Everything about it works as I would have hoped. The rest of this DEPENDS on your 530 acting just like my 430W. I'm betting that it does.
Leave all the wires as they were and turn on the ARINC data flow in both directions and all will be well.
You control the "OBS knob" function from the Dynon HSI when Skyview is working normally. You still control the "OBS button function" on your 530. The way this works properly together is that the 530 will use the ARINC input from Skyview (through the Selected Course label) and then echo that output back to Skyview (through the Selected Course label). Don't adjust the OBS knob on the 106A at all to do this.
Verify this as follows:
1. Put a two point flight plan in the 530. Not just present position to a point, but two points distinct from present position. This will make the exercise more distinct and complete. The 530 map will show the magenta line between present position and the next point.
2. Ensure the 530 is the Skyview current nav source.
3. Press OBS on the 530, verify the OBS annunciator is on.
4. Twist the Skyview course knob a little. The 530 Map should show the magenta line moved to reflect the new course. The local 530 CDI, the 106A CDI, and the Skyview HSI will all show the same deflection and you haven't touched the 106A at all.
5. When you are done twisting the Skyview course knob, press the 530 OBS key again, the annunciator goes out and that last course you selected is now the flight plan. If you took off and engaged the Skyview autopilot in NAV mode, it would smoothly intercept and fly the selected course to the first waypoint and the 530 would sequence to the second waypoint.
6. To return to the original direct flight plan you just re-engage the flight leg the normal way with the double direct to button sequence (I think this is the same between 430 and 530).
7. To prove all is really OK, turn all Skyview screens off and your 530 and 106A will work as before (as if you had not modified anything). You will get an error for missiing ARINC data however.
Thanks Mel J.
