So does anyone have a solid answer to the question? I have the same problem in my logbook because I flew a lot in a Merlin which is right at the edge of 12,500 MTOW, but requires only 1 pilot. if for insurance reasons the aircraft requires 2 pilots. Wouldn't that be a gray area of a required crewmember in the FAR's? What I was thinking of doing was logging the total time for the duratin of the flight and PIC a little less only for the reason that if you're flying from the right seat the tiller is located on the left side which means there is no way you could be sole manipulator of controls? Any inputs?
