I have the notion that for CAT 1 and 2 only TDZ RVR is required but that CAT 3 requires all 3 RVRs (TDZ, MID and RO/SE).
As I take it, the regulation makes no difference between CAT 1, 2 and 3.
Unless a particular airport has some weird weather pattern giving odd RVR readings (such as 600/
100/100) it would be unlikely MID or SE would limit you on a CAT 1. On a CAT 2 a bit more likely, perhaps. On a CAT 3 it could happen, such as 200/
100/100.
CAT.OP.MPA.305 Commencement and continuation of approach
(f) The touchdown zone RVR shall always be controlling. If reported and relevant, the midpoint and stopend RVR shall also be controlling. The minimum RVR value for the midpoint shall be 125 m or the RVR required for the touchdown zone if less, and 75 m for the stopend. For aircraft equipped with a rollout guidance or control system, the minimum RVR value for the midpoint shall be 75 m.
Was that what you were alluding to?
