PDTs Dash's have radio altimiters, and all the required equipment for CAT II approaches - but the pilots are not trained to do CAT II. We leave the DH/MDA set to zero and the RA is really just additional information.
Check your MEL on the RadAlt, and see what happens if it breaks. You lose a lot of nifty whiz-bang stuff, and the cascading MELs get really, really interesting.
First time I ever accepted a plane with that gone had me on the phone to MX with a "WTH?" It's one of those cases where you end up with technically two incompatible MELs... unless you are breaking the RA. The MX procedure is a real eye-opener.
