PICus (Pilot-in-Command Under Supervision) can be logged when a pilot, after successful completion of a flight test on the aircraft, is conducting command tasks while under supervision of a training captain or instructor.

SPIC (Student Pilot-in-Command) can be logged by student pilots on an integrated CPL/IR course when undertaking an I/F flight with an instructor. The instructor may not take control of the aircraft, else the flight becomes Dual.
