At my outfit the touchdown RVR is controlling but the mid/ (if reported/relevant) has to be i.a.w T/O minima - ie. 250 m with no CL, 125 with CL and 75m if rollout guidance is used.
IIRC it was clearly written in the old EU-OPS rules. However, in the new EASA PART-OPS I couldn't find a detailed chapter on minima... Has it been moved elsewhere (AMC, or other place
)
