Regarding requiring dual licences to fly N reg aircraft in Europe! If you remember EASA had a bilateral agreement with the FAA already in place to which they hoped to attach FCL.
Last summer there was a joint meeting between the FAA and EASA to look at ways of bringing a bi lateral about dual licences being declared by EASA as not being their route of choice as well as being legally riddled with potholes for them regarding working pilots in Europe.
