Terminology - Check Airman under JAR-OPS?
US airlines require line checks at given intervals. This checker is called a “Check Airmain” in the FAA terminology.
JAR-OPS has a similar requirement for line-checks.
Question to you guy’s working for various EU carriers: What does your company call the person administering a line check? (in addition to the fact that some of them also might also be TRI/TRE)
