Unfortunately, P2F cadetships have destroyed the civil aviation career structure in Europe. The same pattern is now being replicated in Asia.
This is NOT a pop a those who choose to undertake p2f as if you can finance it, over a 10 year view, it makes good financial sense for the cadet, assuming all goes well and the training is of good quality. I would have done the same myself.
So now we have loads of trapped TP/Regional pilots who can't get career progression in their own country, which is patently unfair.
The only hope of change comes from the airframe insurers who are nervous about the situation and hopefully will lead to more structured cadetship courses which includes a couple of years in a TP operator.
This, of course, does not help anyone still trying to claw their way out of the TP scene. There can even be an argument made for leaving a TP and paying AGAIN to go thru a CTC type scheme so you can get into ESY or similar, if you do the sums over 10 years, you do work out ahead!
