I’m using the C208 and the AP in HDG mode for the around the world trip with Neofly. It wobbles like it does, but otherwise it gets where it is supposed to. Another thing I noticed is that the winds at 8000 to 14000 ft, where most of the legs are flown, are remarkably close to Meteoblue, since accounting for the drift, calculated using the charts and my Pooley’s always brings me within a few miles over 200 nm flights.
