Surely the protected area is the same for CAT 2 & CAT 3. Therefore that should not be a problem. LVO at an airport is LVO. They do have a strange philosophy bin Germany. The met is CAT 2, so the ATIS says the airport is CAT 2. I've asked for a CAT approach and they reply from area control was "the weather is only CAT 2." They do not seem to understand. Thank heavens that the TWR does and they say you do your own thing as LVO is LVO. It would be different if the airfield is only CAT 2 anyway, or the equipment has been downgraded.
