I'd like to bring oldboldpilot's post 1116 to the top again.
Northbeach and others:
Boeing state (quite clearly, to me) - see post 1063:
"The Digital Flight Data Recorder (DFDR) data indicates that the crew was using autopilot B and the autothrottle for an ILS (Instrument Landing System) approach to runway 18R at Amsterdam Schiphol airport."
and that there is an

No dual channel, and I assume no autoland.
MU - normally one is acceptable u/s for Cat I but autopilot that side not used for approach.
