ICP as far as the training goes, up to the fATPL is exactly the same as a Wings Cadet, I don't know whether the MCC (AQC) is included at the end (I think it is not?).
I was told by an ICP cadet that he was assured that in the end they would not just abandon him to fend for himself and would probably get help in being placed. with the current lack of places due to high oil prices etc... I'd imagine CTC Cadets would have priority over ICP guys.
Also, it is not clear whether you have the option to apply to the ATP scheme even if it is closed, since no ICP guy has yet finished there is no clear data on what happens after BOH.
