The FI rating as printed on the licence says "no aerobatics" whilst the CRI rating does not.
There is a very simple explanation for that. The CRI was a new JAA rating and if you look at a JAA FI rating, there is no such thing as "no aerobatics"; "no night"; or "no applied instruments" either. These are hangovers from the pre JAA UK National system that continued because the CAA's computer had not been programmed to cope with the change. Each JAA rating has privileges as defined in JAR-FCL; just because it doesn't have a UK style limitation, doesn't mean that the holder has carte blanch to do what they want, they only have privileges as defined in JAR-FCL 1 or 2. If the holder wishes to add privileges, then they must obtain the relevant qualification.
The UK system was based upon removing "limitations" whilst the JAA system is based upon adding additional qualifications. At least under EASA, the CAA will have to finally get rid of the old UK "limitations"
Think back a few years, a Unrestricted FI was one who could give instrument instruction, because the Applied IF Course (exactly the same as the IRI course) was the only way you could upgrade from AFI to FI and remove the AFI restrictions. Ah, the good old days!
