you cannot handfly unless completely established on final.
You will be pleased to hear thats total rubbish. I regularly hand fly the 777 and thoroughly enjoy keeping my handling skills up to date. Visual approaches are allowed and I encourage co-pilots to do the same. The only restriction I place on myself is to maximise use of the autopilot for "busy" departures such as LHR with weather avoidance requirements and approaches under similar conditions (especially if feeling tired).
Flying with a brand new DEP tomorrow - nice to meet some of the new intake....................
