So is a TRI necessary to conduct initial operating experience? And a TRE necessary to conduct company required line checks?
I guess my confusion is rooted in the fact that the FAA also has a CFI (certified flight instructor) rating, and that goes on your license. But at the same time a CFI rating is not required to give IOE (initial operating experience) and line checks at an airline, even though you've been approved by the FAA to do so.
Bottom line, and the reason I'm asking, is this... If you've got an FAA ATPL, and you're a check airman at your airline, it would look stupid on a resume to have TRI/TRE. ...Right?
