The question of F/O interaction/intervention poses a pratical consideration.
1. F/O is brand new on line, a new boy on the block, not yet steeped in the experience of others, which would breed confidence to say something. Thus says nothing, or not enough, in timidity. I'm sure he said plenty, but to little effect. Looking death in the face is scary.
2. The F/O is senior with lots of confidence and is coming up for a command course. He speaks up, tries to take control, fails and grounds the a/c so disrupting the schedule. Is this being "not company minded" commercially? or showing good command initiative? In the cut throat world of these companies it would be a difficult thought process.
3. What of the F/O inbetween, semi-senior, perhaps less to lose and have the nouse to step in?
I'm surprised someone hasn't opened the male/female F/O can of worms. Would one have behaved differently from the other? Either way, "shut up gringo." is sexless.
Hm?
