The Air Force does not use PIC and SIC designations when calculating flight time. Instead, it uses Primary (PRI) and Secondary (SEC) designations. Primary time is anytime you are occupying a duty position and you are manipulating the controls; the pilot flying. Secondary is the pilot monitoring.

If you are a crew member not occupying a duty position, and thus not logging PRI or SEC time, you then log "OTHER" time. Other time means that you aren't flying or monitoring the airplane. There is also instructor and evaluator time.

PRI + SEC + OTHER + INS + EVAL = TOTAL TIME

When you have multiple crew members on a flight, this causes a lot of angst for the Aircraft Commander during the paperwork. Some people were in the seats, some were not. Some were instructing, some were evaluating, maybe they were in the seats (PRI SEC), maybe not. Then figuring out instrument and night time gets worse.

No where on your official military transcripts does the USAF mention how much PIC time you have. But as ElGuapo stated earlier, most people count the total time after your Aircraft Commander upgrade as PIC. But the airlines know better because they know as an AC, you'll probably be flying with instructors, evaluators, or even other ACs who have been designated as the PIC for the given flight/trip.

Typical of the Air Force, they've managed to take something so simple, such as PIC/SIC, and screwed it all up.
