One one hand CATII/III requires a RVR of not less than 300/200 m on the first segment of the runway.
On the other, on runways equipped with two or more RVR assessment units, one may be inoperative.
Tricky one, but since the table with inoperative equipment does not specify which RVR may be inoperative, you can do the approach as I see it.
For take off you can replace the RVR for the initial part of the take off run with pilot assessment.
I see that as 6 lights = 90 meters and off you go. This is simulator stuff.
If you happen to do this in real life and somebody ask you how many lights you saw? Say 10. Impossible to check.
