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

The ADF is no big deal, but definitely keep the DME. My guess is that
you'll
find more GPS approaches that require DME than require ADF.



Thanks, Matt,

I had no idea that any GPS approaches existed that required DME - 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.
Another is Laramie (WY) Rwy 30.



Matt,

Those approaches can be flown with only the GPS - a DME isn't required. If
you flew them without a GPS, then you'd need the VOR/DME combination.

And all this time I thought the other equipment was required. Oh, well,
better to use overkill then undercut it.

Live and learn.

Point is: if you'll frequently fly approaches that require ADF, keep them
both. I have both and use them just for redundancy. I didn't know that such
redundancy wasn't required, but it didn't cost me anything other than some
minor effort.
