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).
