Thats the point. I think no one said that FOs are running command courses, doing checks etc. The question was: Are FOs involved in training? Yes they are. In a few companies they are even doing sim training. In my previous company FOs did the normal phase and the first sessions of the abnormal phase, then a TRI/TRE continued the training. So where is the problem?
We had very good experience with that, because it is a very good training for the FOs themselves and by the time they have a very good knowledge of the a7c and the procedures.
