Some doubting Thomas’ might be surprised that the better trainees (“young, sharp and motivated”) by the end of the MCC/APS course would be perfectly capable of dealing with this situation and cope well with a 20kt crosswind landing.
You would be amazed what a MPL student is capable of achieving at the end of phase 3.
Phase 4 is the type rating.
From the replies so far it is comforting to know Cadet/MPL first officers graduate on type with command skills notwithstanding basic CPL hours. On completion of the type rating in the simulator it would be a great confidence builder for all pilots regardless of experience levels but particularly MPL or equivalent graduates, to be given the opportunity to fly the aircraft solo from IMC cruise to landing assuming the other pilot is incapacitated.
Because of time limitations of simulator bookings, the practice could start at (say) 20,000 ft and 80 miles from the destination. Radar vectors available but the flight must culminate with an ILS and landing.
