The PRIME role of CC is EMG Ops, service is a secondary (despite what management think, and not an issue on QF anyway
). As such, CC should be asked EP questions before every duty commencement. If they get one wrong, they should be asked another question. If they fail to get this right, they should be stood down. It is that simple. Pilots don't get a second chance with EMG drills, but there are two of us in airline cockpits, thus I concede a second question for CC. It is NOT THAT HARD. If you can't get one out of two EP questions right, I don't want you looking after my family in the event of an EMG!
