I just want to put a different slant on things:
With reference to the above posts, it is quite obvious that a candidate with a CPL will cost less to train.
However if all the airlines took this view, then it is reasonable to expect that eventually, zero hour pilots won't stand a chance of getting a place on a cadet scheme. Consequently paying for a CPL becomes the only option for zero hour'd guys
Similarly a candidate with a type rating (low-hours) cost less to train than a non-type rated pilot .... but if all the airlines took this view on-board than self funded type ratings become the norm and perhaps in time they will become the only option
and i'm sure no one would want this?
Cheers,
