I can add a bit to thatI have the RV-7 and it does have an autopilot, quite an interesting one too, not so basic actually, rather finicky I would say. It does have some interesting options as to how climb and pitch are implemented in a non standard way.
Moreover it works well with the GPS and also with the RXP retrofit. It does have GPSS steering, so you can actually perform the horizontal parts of procedures. It does not have perform, at least I thought, the approach phase of the procedures.
I can add a bit to that
If you've retrofitted an RXPGNS530 WAAS you can actually do coupled LPV approaches.
But it’s the RV7's default GPS that cannot do LPV - it's not WAAS….so be aware of that.
There is an RV config option (default-on) that allows the AP to track an ILS glide slope as well.
So there is still an option for a coupled approach.
This is something a real DFIIVS cannot do, so a purist might want to turn this option off
Setting up a coupled approach takes a few steps; DFIIVS’s own user guide has an outline.
Unfortunately the GNS430 won't fit in the panel because of its screen proportions.
It’s a fair comment that the AP can be finicky at times.
The AP uses a custom feedback controller for its vertical modes.
This controller will be tuned a bit further…it’s best if it’s the last step of beta
