This is as simple as I can make it.....
There appears to be some confusion over the new concept of pilot roles. I hope this post clears up some misunderstandings.
The titles P1,P2, and Co-Pilot have been replaced by Handling Pilot, Non-handling Pilot, Handling Landing Pilot, Non-Handling Landing Pilot, Handling Non-Landing Pilot, and Non Handling Non-Landing Pilot.
The Landing Pilot, is initially the Handling Pilot and will handle the
take-off and landing except in role reversal when he is the Non-Handling Pilot for taxi until the Handling Non-Landing Pilot, hands the Handling to the Landing Pilot at sixty knots. The Non-Landing (Non-Handling, since the Landing Pilot is Handling) Pilot
reads the checklist to the Handling Pilot until after Before Descent
Checklist completion, when the Handling Landing Pilot hands the
handling to the Non-Handling Non-Landing Pilot who then becomes the Handling Non-Landing Pilot.
The Landing Pilot is the Non-Handling Pilot until the "decision
altitude" call, when the Handling Non-Landing Pilot hands the handling to the Non-Handling Landing Pilot, unless the latter calls "go-around", in which case the Handling Non-Landing Pilot, continues Handling and the Non-Handling Landing Pilot continues non-handling until the next call of "land" or "go-around", as appropriate.
I hope this helps out in your quest. It is simple really.
