A full ATPL and 1500 hours. The difference is the "cadet" won't be there.
There is no shortage of pilots. No shortage of experience. Just an abudance of people who will trip over one another to work for nothing, supposedly with the illusion they were trained to bypass the normal hurdles. The employers encourage this as the next best thing to unscrewing the right hand seat and throwing it away. The regulator won't allow them to do the latter, but it is content (for the time being) to allow the former. If employers are required to source from a restricted pool, they have to pay a higher market rate. If they can create an artificial surplus (of no experience pilots) that pressure disappears.
I have no difficulty with whatever additional training and courses are deemed necessary to achieve the requisite for Airline transport flying, but whatever is learned in the process of amassing 1500 hours and an ATPL, can't but assist and benefit in the normal learning process either. This is a cost driven nonsense and it is high time it was stopped and properly regulated.
