AWO is in eu-ops... you can be 125 m trained for T/O and still need the standard 550m for landing.
As for the Citation family, yes their autopilot is CAT2 capable, however a long lasting habit and beliefs, are driving people away from these approvals. ( mainly due to the fact that most of the crews are stepping into a sim once a year only, and that continuous airworthiness programs are not widespread among operators)
As for other bizjets, the lowest I did was Cat3B manual with hud on the 900, 150m/50ft minimas..
Nethertheless, this case will be clarified by the authorities, and since the crew is alive , that will help.. ( unlike the BIG accident..)
