Bookworm,

I think the word you need to look at is: "...Conversion of reported meteorological visibility to RVR".

A reported visibilty can only be what is reported from the relevant ATC unit, in a METAR or in a SPECI. A TAF is - as the word implies - a forecast. Therefore, FCST viz > Min. RVR/visibility = go, FCST viz < Min. RVR/visibility = no-go (or go with 2 alternates in case of destination).

Hope this helps,
Empty
