BillieBob -
when I contacted the CAA my main concern was that they had issued a FI rating on basis that the course was completed at an EASA ATO with an AoC.
Their explanation was that they had no choice but to issue the rating because it fell under EU law regardless of how big a risk that is to aviation safety.
Ironic given what the initials actually stand for. I assume now that the U.K. will not have this problem but just consider how many poorly trained flight crew have been produced by these schools.
