an instrument approach can be commenced regardless of RVR or visiblity but cannot be continued below …ft above the aerodrome if the RVR or visibility is below the approach minima
However, if after passing that height, the reported RVR or vis falls below the minimum the approach may be continued to …
1000 ft
DA/H or MDA/H
If DA/H or MDA/H is above … above the aerodrome the approach cannot be continued into the final approach segment if the RVR is below minima
1000ft
Where RVR is not available for landing equivalent values can be found by converting the prevailing met vis to converted met vis - Converted Met Visibility

Approach with vertical guidance is an instrument approach which utilises lateral and vertical guidance, but does not meet the requirements established for precision approach and landing ops
DH not lower than …ft and RVR not less than …m

To continue an approach below the CAT II DH the pilot must have the required visual references, defined as … centre line, approach or runway edge lights and … crossbar(s) or threshold lighting
