Hi
I absolutely agree, you can operate C525(A) under AOC as multi - pilot. But in my opinion, you cant count these hours to unfreeze your ATPL, because 525(A) are not in CS-23 Commuter or CS-25 category.
I am also not sure about this, and dont want to argue only against. And I would be really happy to log multi pilot hours usable to unfreeze my ATPL on as much small airplane as possible (bceause of that, I am trying to find other types, like mentioned Beechcrafts etc., that could fit commuter cat.)
but according to Part FCL, it doesnt seems to be possible to use small CJs....
You can fly them with friend, you can log multipilot hours, but you cant use these hours to unfreeze ATPL because type doesnt fit EASA rules. As I understand...
