Do I need DME or ADF in an IFR-certified GPS panel?

guess that would make them "GPS-DME" approaches. Can you name some?

One I do fairly often is SDA GPS 12, which is a VOR/DME overlay.

To fly this approach you need either (VOR and DME) or GPS. If you're
flying it with a GPS, you don't need a DME. It's really just for
convenience that they put them both on the same chart.

Looking closer at this approach, I'm a little confused why the OVR
13 DME (CFDKH) fix exists. There's no course change. The MDA is the
same before and after. There's no timer to start. Why is the segment
after Omaha VOR not simply "2800 NoPT to PICAM"?

It's to let you know you're inside the circle :-)
