Just a thought...
I fly an N reg. I hold an FAA IR. I hold a JAA PPL with IMCr.
What I understand is the EIR will be given in exchange for an FAA IR. I hold and IMC which will be grandfathered.
So I see the problem with private N reg and IFR ops has now gone away - I can fly the N reg using the FAA certificate (required), I can fly IFR IAPs in the UK using my IMC (required due to stupid rules), I can fly IFR IN CLASS A AIRSPACE in Euroland due to the EIR (and FAA IR), I can fly IFR anywhere in the world due to FAA IR.
Suddenly there seems very few restrictions, other than perhaps I can't fly an ILS in France.....But actually I would do that anyway due to my Mexican visa which says "this person is a temporary resident of Mexico" on the back....so all of the above is irrelevant?
Am I correct?!
