I don't think its fair to say that ATOs are not delivering the pilots with the skills required, most of the airlines seem perefectly happy with them. You will find plenty of articles suggesting the contrary and that the industry is in a training crisis but they too are usually written by someone trying to pitch a product. Most of the big ATOs do deliver a perfectly reasonable output, its just not quite as good as they would have you believe, the success rates are not really as good as they suggest and above all, they are in it to make money, not to be your mate. I'm not privy to their accounts but I would be surprised if they had not driven the marginal cost of delivering an integrated ATPL below £40K, the rest is profit, and to pay for the very very extensive marketing required to attract the young hopefuls in. The real crisis is yet to come, not with training quality, but with the amount of debt these pilots carry. Integrated training is badly overpriced.
