One could argue that the requirements are there for a reason.
It is interesting that SPIC is allowed as part of the experience required to gain a CPL and to become an FI, but it is not acceptable to add the CRI(ME) to an FI rating. This was an illogical UK ruling made by an administrator, there was no safety case to justify it. Essentially, it only applies to graduates of integrated courses, but as its not included in Part FCL, it will be interesting to see if it survives.
