JenCluse
As I posted earlier, almost certainly the newbie 380 Capt was being checked to the line by the newbie A-380 check captain, who was possibly being checked out by the equally newbie A-380 line manager, or whatever terminology is in use today.
RdC is a line pilot, and if memory serves correctly, was the second QF pilot actually endorsed on the 380.
The reason for the disparity in hours is that there has been very little 380 flying to go around, and training takes a major part of what there is.
