As I understand it, the French concept (which has not been tabled for this month's EASA part-FCL Partnership Group meeting, nor has it been notified to the IAOPA representative), is for an EASA Instrument Rating (Restricted FR), with the restriction being that it may be used only in French airspace.
Much as we in the UK would perhaps like our proven IMC Rating to be re-named as an EASA Instrument Rating (Restricted UK), with the restriction being that the privileges remain those of the current UK IMCR!
Interesting times ahead - particularly given that the FCL.008 NPA still hasn't been released.....
