I also believe they are correct. However, I'm aware that many airlines (my own included) have SOP's which require LVP's to be in operation in order to carry out a CAT II/III approach.
So, with cloud broken at 200' and rvr 550m, and CAT II ils protection procedures in force (but no lvp's in force), our SOP's preclude us from carrying out a CAT II approach.
As I mentioned, I know this is SOP for at least several airlines.
Are these SOP's inadequate?
Or, are procedures for protection of cat II/III ils integrity, low vis procedures, even with 'high' visibility?
