I'm still trying to find the accident report because it seems they could have at 1400 rvr done a cat 2 approach. Maybe briefing a cat 3 approach by AAL procedures would require a rebrief for cat 2 but the FAA doesn't require it. 1200 rvr is the normal cat 2 minimums. I think I could do a 10 second rebrief on changing to a cat 2 approach and I don't think any pilot would initiate a cat 3 with no required roll out visibility.
