RRR, No problemo.
NSEU, I suppose if the roll mode changes from LOC to ROLLOUT, that would inhibit the PVD, so maybe it is not theoretically possible to use it for landing (autoland); however, if the autopilot was not engaged wouldn't the roll mode remain in LOC, thus enabling the PVD?
I'm not suggesting that this would be a good idea, given that in these RVRs you would want to autoland anyway, but just speaking theoretically?
