The problem isn't the training whether we introduce the MPL or not.
The problem is rooting in Management of the Airlines, they view pilots as one poster put it an 'expense and therefore fail to look after their pilots. This has occurred in all professions thus we have shortage throughout.
But fall short of just blaming the Government eventually, the problem lies with the view that pilot training is too expensive! I like REX's advertisement recently.
Also there is more to life of a pilot than in a jumbo. "Training in Irrelevant single engine aircraft" - F**k off!
