AMC1 FCL.050 Recording of flight time
GENERAL
(a) The record of the flights flown should contain at least the following information:
(1) personal details: name(s) and address of the pilot;
(2) for each flight:
(i) name(s) of PIC;
Taking this very literally, you should record the name of the PIC even if that's yourself. Because of this, I have been putting my own surname in the PIC column for the past 20+ years. I know that SELF is universally accepted, so I guess that's seen as an AMOC.
