The example I gave was approach minima without Rollout but as correctly pointed out with rollout a cat3a minima is 200/75/75. It seems to be the consensus that the mid point RVR minima has to equal the TDZ RVR so you would need at least NA/200/75 and not NA/125/75 to make an approach ( no rollout) from above approach ban?
How does the 90m visual segment relate to RVR. Is it basically saying that if you can see 90m in front then this would equate to 125m RVR?
Thanks

You don’t replace the TD with midpoint anymore if the TD RVR is missing (in EASA land anyway). You used to do that but it was removed years ago. For CAT3B (no DH) you just one reading on the aerodrome, it could be on another runway a mile away....
