Forgive my ignorance, but if an experienced and competent training captain can't teach low hours trainees to fly multi-crew jets, who can? If these 1000+hrs guys are coming to him/her with multi-crew jet time, then who taught them when they were obviously newbies? And if they are coming form a single crew, single engine environment (as most probably are in the UK), then how much difference does it really make when neither the newbie or the 1000+hr trainee has any multi-crew experience?
As the obvious spawn of the devil, I'm just curious.
