and assisting a hand flying PNF
How do you "assist" a pilot who is hand flying? Does he really need assistance -eg do you operate his throttles for him? Who "assists" a single pilot IFR?
Surely a competent pilot does not need "assistance" to hand fly his aircraft unless of course he is lacking situational awareness and hasn't a clue about basic flying skills. Then he may need coaching but he should never be in that situation in the first place.
