TRI/TRE rating?

[changer]

Is TRI and TRE an actual rating on a JAA license? Or is it simply another term for "check airman" that we use in the US? (designated by your airline and approved by the FAA to conduct Initial Operating Experience and Line Checks for only that airline)

Would a TRE have the same authority that a DPE (Designated Pilot Examiner) has in the States, that is, to issue a type rating?

thanks in advance
