Rananim, the fact that you believe it is so Inconceivable that a 350 hour guy could pick up a captain on an error, speaks volumes. I am sure CRM gurus the world over are banging thier heads in frustration.
Take the time to read over the posts again on this thread. No one is saying that the FO should 'usurp' the captain, the captain has more experience, thats why he is in the LHS and not the right, however regardless of whether someone has 300 hours or 30,000 hours, mistakes are inherant in human beings nature. To think that one is infallible is a recipe for disaster, furthermore one who doesnt value (not neccesarily accept) the opinions of his crew because he doesn't consider them "a survivor", sounds like an absolute pleasure to fly with.
When I hear of 2500 hour Captains flying alongside 300 hour co-pilots in a 737 in Europe,it makes my blood run cold.The plane is so reliable,the FMS and automation does all the work,and so yes theoretically you should be just fine.But you're hedging your bets
Orrr.... another way of looking at it is that the newly "QUALIFIED" F/O will probably have recently completed an IRT. no autopilot used there my friend. He will have recently completed a line check, would a training captain sign the piece of paper to say a candidate was ready to fly the line unless he genuinely believed him able. Not neccessarily brilliant, but 'able' nonetheless.
Theres a term for people who try and keep people in thier place... its called greasing the pole

, and imho has no place on the flightdeck of a modern airliner, in a modern society. Some may disagree with me, but then again they are probably too busy sat daydreaming of the days when they used to fly the dehavilland comet for BOAC
Happy landings.
