We are not cleared to descend below trans lvl
Sorry, but which regulations are you talking about? In general, you can't descend below the FAF altitude if the weather is below minima, but if the RVR falls down when you're already on the glide, you may continue down to DA(DH).
If there are any local differences, they must be at least described in the approach ban chapter of your jeppesen or equivalent manual (like those 1000' in UK).
Just haven't found any similar restrictions among CIS countries.
