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

There is no legal reason to keep those devices.

However, if you have them, they will certainly aid in situational
awareness.

Thanks, Peter,

I hadn't considering legality, but thanks for that point.

I was assuming the Garmin 430/530/480 to be the GPS unit(s), so I wouldn't
think SA could be improved by keeping the DME or ADF.

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?
