de facto, see post 11. Rate of climb already covered. Incidentally, it's a "should" clause applicable to enroute. I agree it's good airmanship, depending on the phase of flight.
Boeing is not applicable regulator. Let's keep on topic. My specific request is for references to industry standard or regulation. What's applicable to Boeing may not be applicable to other types, i.e. non AT equipped aircraft where VS is manually controlled in VFLC. There may be various personal approaches, hence the request for regulatory guidance.
