"Always listen to your co-pilot,they say.Actually,all that crash demonstrates is that steep cockpit-gradients are not only flawed but lethal".
"You're telling the Captain to listen to someone who cant possibly know anything yet".
I think you're exagerating a bit here to get you're point accross and I'll take that into consideration. But the inexperienced RHS guy, I would argue, is in everyday operation fully capable of knowing when something is wrong.
I've picked up captains on altimetersettings, powersettings, gear, and so on. In safe day to day operation this is whats needed. I fully agree that your example on the gimli glider perhaps would not have had the same outome with a less experienced crew. This is however an extreme situation and we can just hope that these types of events only happen to a crewmember when he/she has passed the 50000 mark in the logbook.
In the meantime, a commander still has to listen to his copilot. What would you say if your 350 hour guy picked you up on an incorrect altimeter setting with a particularily low pressure in high terrain? Would you listen? Even though he couldn't possibly know anything yet? Would you take his advice to select gear down BEFORE the GPWS would have sounded? Not as extreme situations as the gimli glider but still potentially VERY dangerous. These small details are what makes everyday operation safe and it's dependant of that both pilots are listening to each other.
