autopilots and ILS
Hello,
I'm a future RV7A builder and i was just think'n down the road... when I choose an EFIS and autopilot.
I would like to be able to navigate via VOR and GPSS, shoot fully coupled ILS and GPS (including vertical). Do all the various AP's out there (Trio, Tru trak, Dynon, Garmin, AF...etc....) have these capabilities?? I was told that Trio only navigates by GPS.
Thanks for your comments

A Trutrak Digiflight II VSGV with an AFS EFIS and a ARINC 429 converter will fly coupled GPS, VOR, and ILS approaches with vertical guidance. It is the only one I have any experience with.

Whatever answer you receive now will be obsolete by the time you are ready for your panel. Rest assured the capabilities you want will be available from several vendors....avionics continue to advance at a rapid pace.
Best wishes for an enjoyable project!

Ditto! What Sam said is spot on. This stuff is progressing as fast as PC's. The cool part is that whatever you install today will have a software upgrade next week that will add to its already impressive functionality.

This is exactly true for GRT including using their own A/P. Shooting an ILS approach while coupled to the A/P is extremely simple and accurate.

Most APs depend on the EFIS to convert the older analog data (i.e. ILS) to appropriate steering commands. The only one that I'm aware that natively supports everything is the TruTrak Sorcerer. Fortunately, with most of the popular EFIS solutions, there is no real need to spend the extra $$ for those features.

I have a question too
Can I ask those in the know if my GNS430 and Trutrak ADI II is suposed to fly a VOR approach. Tried one this morning while practising IF and it showed the approach on the GNS430 screen but did not want to fly it.
Is it normal or did I do something wrong?

Your TT A/P can not receive nor follow VOR course guildlines directly from the 430 but if you have an EIFS like GRT or AFS, then GNS430 will send the course guidelines to the EIFS and the EIFS can drive the A/P.
Hope this helps.

Thank you very much.
Strange that it will fly a flight plan or a direct to course but not the VOR

You can certainly put the VOR as your waypoint and it will fly to it but not all VOR approaches are located in an airport. These are two completely different thing.
But it should follow to a VOR as a way point OK.
