Narrative:

I was the relief pilot on break and got a call from the captain that they needed me up front. We had an elms P110; fuel jettison; door lock 1L/2L/3L/4L; cargo heat; C1 hydraulic pump and several other EICAS and status messages. We made a sat call to dispatch and got a patch to maintenance control. We attempted to dump fuel but the fuel dump system was inoperative. After reviewing the landing data chart we landed at 519K pounds. The runway was snow covered but braking action was reported as good by a company aircraft shortly before we landed.
