My question is actually, can pilot vis replace a touchdown RVR that is below limits(localized phenomenon)?
From the horse's mouth, in Europe - EU-OPS Appendix 1 to OPS 1.430
Note 3: The reported RVR/visibility value representative of the initial part of the take-off run can be replaced by pilot assessment.
Note 4: The required RVR value must be achieved for all of the relevant RVR reporting points with the exception given in Note 3 above
So Yes, the initial (you call it touchdown?) RVR can be replaced. This is true if you are using a take-off minima of 150 m.
However, if you are operating with a take-off minima of 125 m there are further considerations which of one is:
(E) the required RVR value has been achieved for all of the relevant RVR reporting points
That's what the regs say, but reading my OM-A they've muddied the waters a bit by using a different wording. I can't say exactly what I am allowed to do. The question then is if OM-A takes legal precedence over EU-OPS.
