Rananim, in response to you question I would obviously say you want the more experienced guy

. BUT...and its a big But, if you had offered a third option ... i'd prefer to have them both. And in reality, in a modern jet airliner that is exactly what I have got. IE TWO PILOTS. this is the point you are missing, it is a multi crew environment

. I appreciate what you are saying with regards to experience. However by ignoring the guy in the RHS you are only steepening the cockpit gradient. It is all good and well saying that we should be shallowing it by only putting experienced guys in the RHS, but again you have failed to address how one may go about gaining experience.
And the co-pilot is straight out of flight school,he's got 600 hours under his belt,300 on type.He's conscientious too,knows all the SOP's and is a pleasure to fly with
So 50% of his experience is on the aeroplane he will fly for the rest of his life. just out of flight school, therefore books and limitations will be fresh in his memory. No bad habits. wont get confused and revert to previous behaviour under times of high stress (as often happens, of course being a champion of excellent crm you will know that

) You imply that when one becomes a commercial pilot you simply get out of your cessna and up the steps into the big stuff. What about Type rating courses, CRM courses, 40+ simulator sessions that involve very little normal flight at all, base checks, line checks, line training ...etc...? "Knows all his SOPS and is a pleasure to fly with"... for me thats half the battle won. Who would YOU rather... a cockpit where the FO is scared of doing anything lest the captains ever so experienced had smite him from above, or alternatively a cockpit in which the atmosphere is relaxed, ideas flow freely regardless of whether it is an normal or an abnormal situation?
Its not about economics at all, its about the fact that commercial aviation is growing at an astounding rate and people will apply to these cadet schemes (myself included) because they know to sit in a cessna, twin otter, tiger moth...whatever and then attempt to get a job will be nigh on impossible (or hard at least) , due to the fact that there are pole greasers at every stage of thier training and career, who wont give them a job because they lack experience yet they have no way of gaining experience...because they can't get a job. Sound familiar? probably
Happy landings.
