Sorry to interrupt, guys, but I still haven't had an answer to my
question:
So what happened on the copilot's leg in half-decent weather? Was there not a complete role-reversal?
Not sure if any airline currently allows copilots to do landings when the wx is worse than Cat I, so I'm not thinking of that. When I started doing monitored approaches in 1988 as a captain on A320s in BA, we tried to arrange the tour's flying to enable the F/O to get half the landings where possible. Ergo, the captains did half the descents and approaches up to the point when the F/O was visual.
