In this context, SPIC is a red herring since it can be claimed only as part of an integrated course. In the case of a 'checkout' flight conducted by other than the holder of an instructor certificate, only one person may claim PIC and all other occupants are passengers. If the 'checkout' flight is conducted by the holder of an instructor certificate, then either the instructor or the person being checked out may log the flight as PIC, but not both. If the instructor acts as such (i.e. gives instruction) during the flight, he/she may log PIC and the 'checkee' must record the flight as P/ut.
