TopTrump, right up until HUPRA was used in anger. Made a ‘999 Special’ telly prog about it too. Anyway, back to topic.
NWS is required on the 'J' if assymetric, even after V1 (don't ask me how it got certified, but it did) never mind the x-wind landing stuff. Giving control of such an aircraft to someone with only 180hrsTT when the Captain can’t override them is not a sensible move!
Co's, RHS 'til experienced enough - however long or short a time that may take - LHS after that no problem. No reason, not even for cost saving, to make it earlier.
It's not co-pilot bashing. It's keeping the aircraft as safe as practical.
