How about if I'm the "acting" PIC and I'm in the bunk on a KC-10A and two pilots who are not in command are flying the jet. Military rules I log "other". Per 61.51 I log PIC? For NetJets I log zero "other". How do you log it as a 777 captain in the bunk as "acting" PIC? It would be nice if they didn't leave it up to interpretation.
