I have a non-touch AFS 5600 that I need to add an autopilot to the panel. I am in the “panel” portion of the built, not a flying airplane. My initial thought was to use the TruTrak Gemini AP thru the ARINC adaptor. The plane will have a remote mount Val NAV 2KR. I was not intending on installing an IFR navigator and only use the GPS off the AFS system. I’m trying to decide if I should upgrade the 5600 (probably $2k) and buy Dynon servos and control head, or just buy the TruTrak. As I have never flown an AP before, I’m not sure if one AP is more capable than the other. I do want the ability to use the AP to fly approaches.

although I have a 5600T and a Vizion 385 that just work wonderfully, since you have not committed to servos yet, I would just go with the AFS/DYNON system -- the integration would be very smooth and Rob and the Dynon folks would be a great resource.

Ditto to Ron's comment.

The ?integrated? autopilots work well, and tend to be about $1K cheaper than the stand alone ones. But, for actual IMC work, the stand-alone units do offer an additional layer of backup. Up to you to decide.
BTW, don?t overlook Trio. They make a great autopilot.

Servos on the Sv-network (Dynon/AFS), you can move the Master EFIS pretty quickly should the PFD fail. There are also a couple other minor advantages over the Trutrak heads.

My Vizion and servos, as well as a Gemini PFD May be up for sale shortly.

If it helps you, I would be in the market for them. That would be a nice setup for me. Guessing your upgrade is due to a touch upgrade?

You're correct: part of the $$/risk equation is that a second EFIS or air-data computer can be similar to the cost differential for a self-contained autopilot. Some different failure modes to be considered. But it appeared to me that the OP is talking about a single EFIS, so a non-integrated autopilot does mitigate against some, but not all, failure modes. OTOH since he specifically stated that he is not interested in a TSO'd gps navigator, all approved approaches (VOR/ILS) have to go thru his EFIS to drive his autopilot, be it a Dynon, Gemini, or Trio. Bottom line: For IFR work, the entire system - redundancies, backups, failure modes - needs to evaluated to see if it is with in the PIC's tolerance for risk.

A few years back, I had a failure in one of my first gen GRT screens-----the one that drove the A/P.

I lost the ability to follow a GPS driven course, but the internal magician inside the TruTrak head would still hold altitude and heading.

Just something to consider.

I have the vizion 385 autopilot, it is rock solid and it flies a beautiful approach. The only way it will get removed is that i totally lose my mind and redo the panel with an all garmin g3x setup.

One very nice thing about having an integrated AP is that it knows what your attitude is and can right the plane, should you engage it after an upset.

Trutrak Gemini has same function in its stand alone AP.

Only it doesn't know as much as your EFIS does.

Unless, of course, the reason for the upset was that the EFIS failed.
