Same thing in FAA land. The crew has to know the capability of their aircraft and what they are trained for. The FAA is slowly getting away from labeling approaches CAT 3A or CAT 3B or CAT 3C. Now the updated approach plate will just have a RVR. In a plane with a fail operational autopilot the crew might be able to shoot approach with 300 RVR and no DH. But a different airplane with a fail passive autopilot might be limited to 700 RVR and have a 50 foot DH.
