What if MDH>1000ft agl, do they report +10km RVR 
?
So I haven’t seen this answered and I’m aware the rules for part-nco have changed. Say though, that you are flying part-cat and you are visual with the runway and can remain visual, but RVR is reported as being below minimums could you continue through the 1000 ft / FAP?
Under IFR, you can legally descend bellow FAF/1000ft agl to land off airport, land before threshold, or circle to land on another runway using visual references on direct visual approach (VA) or circle approach (CTL), for these the visbility is “pilot interpreted”…the measured RVR is only controlling on threshold & touchdown for the IFR instrument runway for which that RVR is published
You can cancel IFR and fly VFR and land while you “maintain cockpit VMC”, if it’s two crew you may need to agree with the other pilot on a visbility figure
I have not tried any of the above, just theoretical understanding
Another theoritical question, if RVR at runway mid point = 5000m and RVR at touchdown point is 500m due to fog blanket, can I land very long?
Your scenario is very plausible with shallow fog layers, you can see runway numbers, identify thresholds and spot the tower as you pass overhead at 1000ft agl with good vertical visbility, you can’t takeoff or land on ILS as it’s banned by RVR, I saw this at Exeter once, after few orbits we diverted to Dunkeswell that was sitting on the hill with VMC on top conditions !

So what would happen to your flight visibility as you actually were about to touch down in these conditions?
It will drop to 400m on surface along the runway, at 500ft agl you are still sitting on top with 100km forward visibility

Can you land on runway? likely no, unless you are VTOL
That was my point…
I was not tempted by ILS to DA to have a look…I gather it would have been legal to descend under 1000ft agl even with no intention to land ?
This thread references the change in the approach ban regulation.
