Thanks Henry, I'll check it out.
I think lvp's are mandatory with conditions below 200' cloud base and rvr 550m (i.e. the bottom line for cat I).
However, with conditions at these cat I limits, ATC report 'cat II approaches available and protection in place'. Despite the fact that we would like to avail of the cat II, we cannot because ATC will not enforce lvp's (because from their perspective they are not necessary), even though lvp's are required for such an approach as per SOP's.
