They have their own ANO equivalent and it's based on the UK one so similar.
The IMCR is the UK IMCR
The Jersey 'ANO' allows for the 10k viz requirement for SVFR in Class A to be reduced to 3k if the holder has an IMCR
The old 'get into class D and try and get IFR with the IMCR' has gone round and round. Apart from the fact that the procedures include flying outside the Class D (and I know you could argue you might be able to do a short ILS but that won't cut the mustard) - think about it - how would a controller be able to vector you in the event of a missed approach or other ATC related requirement and figured out he's got to keep you in his class D? If he wants to put you in the hold you'll be back in class A
If all you want to do is shoot the ILS and you're on an SVFR clearance just ask to fly the ILS and they'll vector you in (or let you do a procedural one if you want).
