Well, if the PF is handflying he of course doesn't dial in the altitude cleared and doesn't point to it, its the PM in that case while the PF replies.
Altitude assigned...no.
However, make selections on the FMS while hand-flying?
Yup, done all the time (and for a
very long time) at some companies.
Some airlines actually train pilots how to fly the airplane, not spout verbal nonsense....endlessly.
I really do have to laugh at some of the younger guys...they are relatively new, yet, seem to 'know all about it'...according to ....them.
