how they do it, they need to turn up with an acceptable level of knowledge. I know 3 FO's this last year who have been chopped through lack of flying ability and knowledge which is more than the previous 7 years put together. And they payed for there own type ratings. 1 was mod and the other 2 Intergrated.
The developing a FO's experence base is something we can deal with and for myself I get a great deal of pleasure doing. I am not there though to hand feed them information which they have supposed to know for there PPL never mind CPL.
