Hamilton - extensive coverage on PPrune if you search for it. It is down to your regulatory authority to survey and assess an MDA/H as 'fit' to be used as a DA/H and then you can, on a CANP (CFDA) approach only. Otherwise you add xxx' or increase RVR as stated before - this is covered in Appendix 1 (New) to EUOPS 1.430 and an excellent explanation of the whole thing is on that previous thread. As always, Hamilton, your company Ops manual is your reference. In simple terms if it doesn't say you can you can't! - what does that say?
Here, with acknowledgement to Jepp, is what they say:
Minimums:
CDFA will be the Standard on Jeppesen charts
non-CDFA only in exceptional cases
Jeppesen will publish DA(H) instead of MDA(H) for CDFA approaches
Jeppesen will not use an add-on when publishing a DA(H),
to use or not use an add-on is still the operators responsibility
Jeppesen will publish MDA(H) for non-CDFA approaches
PS This has to be one of the most muddled changes I have seen for years.
