Alex. Thank you for the explanation to the PICUS question.
As for unfreezing a frozen ATPL.
If you are employed by a UK airline with a (f)ATPL at age 19, once you are 21 with 1500 hours and 500 multi crew. Your yearly check ride should constitute a conversion from frozen to full ATPL.
But if you are working in the US as F/O under Pt 135 with a Comm/Inst/Multi and turn 21 with 1500 hours and your ATP written passed, your yearly check ride will also be your SIC ATP ride and SIC type rating. When you turn 23 it will be upgraded to a PIC type rating.
But you will still have to unfreeze your (f)ATPL which would require renting a simulator in Europe to do the same check ride again, or buying a EASA examiner a ticket to the US and expenses to watch you in a simulator.
Killing two birds with one stone however, would be the new Norwegian WOW Airlines. Where you get two years flying with a FAA ATP license before having to convert to a EASA ATPL. Sounds like you can spend two years with BGS study material, being based in Florida and taking the exams in Orlando, and use Norwegians simulators for the EASA check ride. Brilliant.
