In this case the RNAV(RNP) VIS MINIMA is 900M for CAT C Aircraft. I have been led to believe that the Company MINIMA for this approach is 1500M.
Isn't the AB330 a CAT D airplane?
Another factor is this NOTAM, which was in effect on the date of the accident:
V0071/15 - [DOD PROCEDURAL NOTAM] RUNWAY DISPLACED. RUNWAY 02 THRESHOLD DISPLACED 120 METERS (400 FT) UNTIL FURTHER NOTICE. 09 APR 20:05 2015 UNTIL 01 JUN 00:01 2015. CREATED: 09 APR 20:05 2015
In the U.S., at least, the RNP AR would have been NOTAMed OTS until the threshold is no longer displaced.
