Not a pilot, but a question starting from this quote:
A sequence of mistakes on a July 28 evening flight from Newcastle to Melbourne left the pilot flying the plane - a cadet recruit with just 300 hours Airbus flying experience - overwhelmed. The captain sitting next to him was so busy trying to recover the situation that his capacity was also compromised.
There appears to be almost universal condemnation amongst pilots about having a low-hours pilot in the RHS, not just here, but in other threads too. Everybody starts with NIL hours experience on type, so how are pilots expected to transition from NIL hours to 'adequate experience' (my words, whatever the criteria might be) without at some stage being in the RHS with minimal hours?
