If you pay attention to the message on the 430, it says something to the effect that the GPS coordinates are only for a reference and not for guidance.
For an ILS/VOR approach, for it to be legal, you must select the VLOC button to point to the VOR and NOT GPS on the 430. Only then you are sending the Loc/glideslope signal to the auto pilot and in that case this can be done only via a supported EIFS and not directly from 430.

What's a VOR?
Will it even be available when you're ready to fly?
Check out this new thread.

You need the AP IV and either an SL30 or a GNS430/530 (and I assume a GTN650/750) and our TS-43 ARINC Module. That'll let you fly the ILS and display the VOR. It won't fly the VOR off the actual VOR signal at this time.

So Lucas, the vor/ils is an analog signal? And the efis converts it to a digital signal so the AP can use it? Does the arinc box do this also?

The 430 can also output vor/loc/gs data over the NAV ARINC ports. Some EFIS units can take this data and transform it into GPSS/GPSV signals that the GPSS/GPSV enabled autopilots can understand.
The ADI pilot does not have ARINC ports so won't accept GPSS/GPSV.
Some EFIS units can also convert this ARINC NAV data to NMEA data that the ADI pilot can understand but this will not have any vertical guidance nor will it be GPS steering (it will overfly waypoints and then turn back).

Yes and no.  The ARINC box takes the digital ARINC VOR/ILS output of a 430/530 and converts it to an RS232 signal that the EFIS and EFIS AP can use.

Dual ARINC 429 inputs
Hey Lucas,
When the Gemini AP is released will it have dual ARINC 429 inputs?????  It would be nice because the Vertial guidance is not yet implemented into the Skyview software so I dont want to send the AP control through the Skyview.
The GTN650 has an ARINC 429 output for both NAV and GPS data and it would be nice to just have it all integrated into the Gemini and not have to use an External switch.
By the way I dont know if this is possible but would be nice.

The specs on the Gemini AP only show GPSS/GPSV capability not NAV....Typically TT has only had this feature on their Sorcerer AP. IF you are expecting to couple the Gemini to an ILS directly, I believe you will be disappointed.
Dynon historically has not provided full EFIS control of a third party AP. So even when they do implement vertical coupling for the Skyview using the Dynon AP, not sure what if anything you will gain in a setup with a third party AP.

Thanks Brandel,
I was thinking it may be that way. however with the GNT 650 outputing arinc 429 Nav data instead of the analog nav signals I think it should be an easy interface.
Could be wrong.
