S76A - What's an autopilot?
S76C+/++
Approach - 4q : NAV, IAS, Alt Pre then Alt Selected
Go Around - Go Around button then when established NAV/Bug, IAS, Alt Pre/Alt Selected
Cruise - NAV, Alt Selected
In bumpy conditions in cruise AS, being 4q just causes the AP to hunt, so 3q (trim, NAV, Alt) works best and then just set airspeed with the collective.
Most if not all the guys I have flown with do it like this.
