We were trained on the RNP stuff in the sim and the approaches could only be flown in VMC conditions when I was there. After so many months of looking at the data of the VMC approaches, the FAA was suppose to approve them to be flown in IMC. It took them a couple of years to get RNP 0.3 certified, but they now fly them in IMC.
FWIW, the guys going through 320 training are now being qualified on RNP 0.3 approaches. We were trained on them and told we could do them in VMC conditions if we have the approach plates (which we don't). The guys in MSP said we should have approval within a year and everyone will be trained during recurrent training.
