It is permissible to dispatch in such a case, provided two alternates have been selected and fuel for the furthest is carried. Again, this is under EASA, other jurisdictions may have different rules.

Thank you for your reply.
I think so too
RVR is just observation value.
So if I want to dispatch this VIS 600m, I have to provide two alternate. (except short flight)

and If possible, can you tell me where I can see EASA regulation regarding this matter?
