Autopilot wouldn't capture on ILS

[t4murphy]

Approach into Nashville BNA using the TDS GPS. The steam instruments indicated the glide slope and center line but wouldn't capture for approach. Otherwise I love flying these 2 AC. The Baron was the AC I was using at the time

This happened to me too with the Bonanza. I have had successful ILS captures, but it isn't consistent for me.

I'm seeing this too.

I suspect this may be specific to the TDS GTNXi. I've tried two ILS approaches with it, both didn't capture. I then did an ILS approach with the GNS 530 for comparison, and that worked perfectly. Will need to do some more testing, but for now it looks to me as if it may be an issue with the TDS.

Hello,

To clarify this from the TDS Sim Software side of things.

Whenever the GPS/VLOC switch is in VLOC position, as in when flying an ILS approach, it is the MSFS autopilot system/logic which takes over. The TDS GTNXi Pro does not handle any logic or handles anything. The TDS GTNXi Pro full follows the official MSFS SDK in terms of autopilot/logic.
Fine tuning of ILS capture is performed via the aircraft's config files, the TDS GTNXi does not have access to these files.

From the TDS side, we are working on a custom autopilot, as a courtesy to our customers, but this is a very laborious process. Not to worry, we have the best intention to our users to continually improve the TDS GTNXi Pro!
