JAA | Licensing Class and Type Ratings - List of Aeroplanes List of JAA type ratings(not sure how recent this list is) The cessna 208 is on it so you would need the rating. Now do Susi provide the JAA rating for you on the 208 or do they provide an ICAO one?( if such exists) And is there a differece between the two?
All questions for you to ask the CAA. Be sure you can log those hours before you go out there.
