ATP
5N, what CAE makes sense, however, the fact you didn't have an ATP at the time made no difference. Under the FAA structure, to get a full unrestricted type, you have to already have a jt type rating on your certificate, or have 500 hours SIC in type, or 1000 hours SIC in a similar aircraft, or do a actual check ride in the aircraft. If you don't, you can be issued a restricted type rating that requires you to get 25 hours of IOE within a certain period of time, I believe it is 6 months) then go to the FAA with proof and they remove the restriction.
Babisiliop, as Marker stated, you will have to take a checkride. It can be done by a DPE. Some TCE's are DPE's also.
