Clear as mud. In the CJ I would keep the autopilot coupled and monitor the altitudes shown on the plate. Never anything other than perfect.
Lots of pilots doing that today. Are you suggesting a pilot must monitor with Baro Vnav. But not with LPV.? I hope not!
Many professional pilots believe they have been carrying out Baro Vnav approaches at places like Wollongong.
Surely the approach must be as or more accurate as an approach without baro and temperature adjustment and manually flown.
