Icao Cpl/atpl
Historically, it has been true that "professional" pilots (CPL/ATP) have got better grandfather treatment than mere PPLs.
This is why I have always recommended to anybody doing the FAA PPL/IR to put in a bit more work and get a CPL/IR, and I did that myself.
Plus I run both CAA and FAA Class 1 medicals, just as an insurance policy, to lock-in Demonstrated Ability for ever... done concurrently with the right AME, this costs hardly more than just one Class 2.
Some original versions of the EASA stuff did look like this might mean something, but I have lost track of it now... it would be interesting to find an FAA CPL/IR -> EASA PPL/IR (no use for an FAA CPL here anyway) easier than an FAA PPL/IR -> EASA PPL/IR.
What do you think?
