Rookie? Babysit? Take command of his aircraft?! What planet do you live on? In today's real world both pilots are equally qualified to fly the aeroplane the main difference being that one has to sign the paperwork. To assume only the Captain is truly capable of aviating is to ask for another AirBlue crash (next thread down) where it was actually the FO that could fly and the Captain that killed them all.
The eternal FO argument. It should be the question in what world
you live!
Maybe all FOs fly better than the skippers, at least in their opinion, but it takes way more to operate an airliner. And these add-ons are not god given, even to the best FO.
It takes a thorough training, a decent amount of experience and a serene assessment to occupy the left hand seat. Although most bean counting greedy manager would disagree, reading recent accident reports, where aviation was supposed to become safer and safer, show that this has become the achilles heel of civil aviation: Shortcuts in training (due bean counting greed), shortfalls in assessment (too lenient on favored groups/persons due to national agendas) abbreviated careers (due to both above) lead to people sitting up front without the personal tools needed. They might be raw diamonds, but they are to roughly cut for the job.
AF447 shows perfectly well that there was a pilot flying in the RHS who had not the basic flying skills, a pilot acting in command on the LHS who had not the skills to command and analyze a critical situation and finally the captain showing up on deck who had not the leadership skills to either direct or take over a terminally critical situation.
All things that might and should have been trained, repeated and assessed more thoroughly.
