Synthetic Vision

During the last several flights, I have noticed that the ownship symbol on my IFD540's MAP-SVS page has shown a "fixed" level orientation regardless of whether my airplane is turning, climbing, or descending or any combination of these. Both the iPad and PC IFD simulators show the ownship symbol "banking" during turns and "pitching" during climbs and descents on the MAP-SVS page. Other than that, my MAP-SVS page looks normal with respect to terrain, routes, shadows, traffic, FLTA, and grid lines.

I seem to recall a document issued by Avidyne describing the MAP-SVS ownship depiction behavior on the IFD's; however, cannot currently find it (it may have been the original draft IFD540 PG for software version 10.2).  The current IFD540 PG does not mention anything about the ownship symbol "banking" or "pitching" with flight path changes.

I thought when I upgraded to 10.2.0 that I looked for this ownship behavior on the MAP-SVS page; however, may have not have specifically noticed it (or lack of it) while taking in all the other cool changes that came with software 10.2.0.

I was curious if anyone else on the forum has noticed this ownship behavior (or lack of) with their IFD?

While the iPad and PC IFD simulators exhibit this ownship behavior, I also noticed that the IFD100's MAP-SVS ownship always stays "fixed" on both my iPad mini and iPad Pro when connected to either my airplane's IFD540 or the iPad IFD simulator across a WiFi network. Interestingly enough, in researching this, I just viewed an AvWeb video from Sun & Fun 2016 regarding Synthetic Vision and the announced 10.2 update and IFD100. In that video, it can clearly be seen that the demo IFD100's MAP-SVS ownship was "banking" during turns.

This leads me to ask whether Avidyne removed this ownship behavior entirely from the release 10.2.0; however, did not take it out of the IFD simulators?

FWIW - my IFD540 is in a Piper Archer with no heading or air data computer inputs.

Avidyne Tech Support wanted a picture of what I was talking about; however, I won't be able to get that for a few days. They also inquired if I was near my flight plan route when testing this behavior; I was about half the time.

Is anyone else bothered by the 1.2" wide magenta line at the bottom of the display when you are on course with SVS?  Come On!! do we really need that fat a line to stay on course?  It is very distracting when in IFR conditions like I was on the way to Oshkosh with rain on the windshield for 90 min.  It kind of masks other info.  I would toggle back to MAP and go back to my vacuum AI to keep the dirty side down.  BTW The SVS is in my IFD550.

Synthetic vision is pretty much of a gimmick for me with the 540, albeit a neat one.

I think if you do NOT have an electronic PFD/MFD of some sort, then the IFD540 -> IFD550 would be a solid upgrade.
