Some further comments: One could distinguish between CFI firend who is just sitting in right seat of his friend's new airplane and friend (or relative) is fully current, fully rated, and sole manipulator. And maybe they switch seats on next leg. Really just flying for flying's sake. But that goes more to whether CFI is "acting" as an authorized instructor rather than whether he is authorized by FAA for the operation in question. Here's another hypo: Same facts as original post, with clarification that the CFI is not a CFII. And the flight is a BFR. The instrument-rated private pilot is current for all of his privileges. All goes well, except it's a coastal airport and some localized low stratus has crept in. IFR approach back into airport. Actual IMC during descent. You can modify the hypo some more if you want, but idea is there's actual on the return. Can the CFI who is not a CFII but who is conducting BFR log the actual instrument time as his own actual instrument PIC? My thinking is in general the CFI needs to be a CFII to log actual instrument PIC while acting as authorized flight instructor. But this CFI is authorized to conduct a BFR of this private pilot. With focus on whether this CFI can log the actual instrument PIC, your thoughts?
