Air France Crash Suggests Inadequate Training | AVIATION WEEK
– which
PJ2 has provided a link to on the Tech Log thread, states that the less-experienced co-pilot was the PF in the RHS. I know nothing of Air France protocols, but is it possible that he was the P2 or even the P1U/S (pilot-in-command under-supervision) on the GIG-CDG leg, and that the more-experienced co-pilot was acting as the relief pilot? How does a junior co-pilot get regular landings, if so qualified? This one seems to have been qualified. (I am assuming that the relief pilot is the one who occupies the P3 seat for T/O and landing, and in the cruise moves into the seat of whichever pilot is taking a rest-break.)
