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

There are a considerable number of GPS approaches that are overlays of NDB
approaches. Normally, you would use the improved percision of the GPS and
fly it that way. Now the 430/530 requires that your database be current
in order to legally fly an approach (at least with the AFMS that I have).

My 480 FMS only requires me to know the approach info is right.
Of course the real answer is if you're going to fly IFR, you're going
to have to keep your NAVDATA (charts, GPS databases, etc... up to date).

Yup, a big advantage of the 480 over the 430/530.

Has anyone ever attempted to get a FMS approved for a 430/530 that has
verbage like the 480 so that you could still do an approach with an
expired DB?

Not with any FSDO around here for sure. I've even got the stupid
GPS/VOR annunciators because my 480 is three inches too far to the
right to qualify for the exemption.
