NCO Commencement and continuation of approach

My understanding is that RVR 550 m is required by regulation for all NCO operations, while the RVR/VIS part of any specific "applicable minima" is determined by the pilot. While a procedure would typically have an OCA(H) that must be respected when determining (M)DA, it would strictly not require a particular VIS/RVR. Indeed the tabulated RVR/VIS in AMC (it is AMC2 NCO.OP.110 in the new Decision 2022/012/R) is a well proven guideline, but the pilot is actually free to establish his own, according to NCO.GEN.101.

Hi Henrik, thanks for replay. so, if I establish for a procedure a required RVR of 1000m, where am I suppose to archive this value? at 1000 ft ?

I think that is a very good question, as the approach may be continued as long as RVR is at least 550 m. The closest thing to an answer to your question that I can find, is GM1(d) NCO.OP.210:
"If the RVR is less than the RVR calculated in accordance with AMC3 NCO.OP.110, a go-around is likely to be necessary since visual reference may not be established at the DH, or at the MDH at a point where a stable approach to landing in the TDZ remains possible. ... The pilot-in-command should consider available options, based on a thorough assessment of risk, such as diverting to an alternate, before commencing the approach."
