My point is that on initial training jet fleet a new copilot with a low number of sectors let loose on a normal line captain without a safety pilot can be a liability.
Simulator flying is not line flying and automatics aren’t a substitute for skill and experience.
When the whale was introduced a mate who had been fleet training manager on a smaller Bus phoned me as he was dropped in the deep end having to train from both seats without anyone supervising..in his 60s it was too much INHO.
