I have spent most of my career in the military and just started flying for a civilian flight school, so I am still trying to learn some of the gray areas of the civilian world.
I am a CFI/CFII. An aircraft broke down and the maintainer needed to fly over. He needed me to fly with him (in a Cessna 172) since he did not have a medical. I was there making sure the flight went ok but he was the sole manipulator of the controls.
I assume for the flight, I am "acting PIC." Can I log that as PIC even though I did not touch the controls? It would not have to be dual received/given since I was not instructing, just me being there for safety?
It was only 0.4, it's not that I care about losing out on that 0.4, I am just curious and really like my logbook to be as accurate as it can be.
