CAT II, without CAT I reversion question?

[BLACK_BUSH]

That would be my understanding as well Bally Heck.
After passing 1000ft all RVR information is advisory only and you are quite legally permitted to descend to the minima set.
Our fleet Lo Vis procedures make provision for reversion toCATI"if the relevantCATIminima has been set on servo altimeters,andCATIprocedures have been discussed in the pre-descent briefing".
All companies have provision for ground/airborne equipment failures above and below 1000ft in their CATII/III procedures and most have the caveat "At the Captain's discretion an approach may be continued".
FWIW in my humble opinion,if any doubt exists about the safe conclusion of any approach,a Go-Around and reasessment would be the better option.
