michelda, at the same time lack of TDZ RVR assessment has no effect on CAT I ILS approach. I presume we're talking about Napoli here judging based on the RWY directions and other particularities. If so, 10-9 under "ADDITIONAL RWY INFO" shows availability of RVR readings for RWY 24 and lack of such for 06. Perhaps it's due to LOC offset? Anyways, here te way to go would be obtaining the required RVR through conversion of prevailing visibility. As it was 400 m at night but required RVR is 900 you were short of 100 m to be eligible for approach.
