Does the PIC log the time while in rest? Yes, the entire flight is logged because he/she is a required crewmember.

SIC should log the entire flight and add a separate column for either in-seat or in-rest to answer the inevitable question of how much was actual stick time. It's the whole acting vs logging issue.

On a related issue, FO's can technically log PIC on their legs as PF (sole manipulator), but nobody in 121 really counts it. Likewise, they CAN log the entire flight as SIC, but some employers will want it separated by rest/in-seat.

So, log it all as a required crewmember, but also have a way to track how much of it was in-seat.

On an augmented flight an FO is the PIC even on the flight release for the time the CA is in the bunk. In our shop an FO signs in as PIC for that time.

I obviously wouldn't log it though, but I know a guy who got in UPS using that time, as he was legally designated as PIC during the flight. Must have interviewed really well.

I kept a separate category - Copilot/PIC. Logged the actual legs I flew under that. That's the 'sole manipulator' column. Removes any doubt. Block to block. Didn't track OFF - ON times.

When airlines asked for PIC time a decade ago they specifically said "did you sign of the airplane AND were you in charge?" Flying in the left seat, PIC on the flight plan, but the real Captain in the right seat, gets into a judgement call area IMO. The airlines counted that as SIC time.

exactly. Acting and logging are different standards. Since FO’s are typed, the way you guys do it kinda makes sense in a post ATP rule industry.

121’s still want actual - signed for the plane - time…. And it sounds like your shop just muddied that water.

The FAA equivalent of a participation trophy.

Bingo. Which is why the airlines ask "were you the Captain that actually signed for the aircraft?"

Part 135 lots of guys want to fly left seat, especially on their legs. Beats me why. If they wanted to seat swap I normally flew me legs from the right seat. Beats moving gear every leg. So the FO, either PM or PF, would be in the left seat while I was the lowly 'right seater.' They can be in the left seat, flying the leg, but they're not the final decision maker.

I understand "sole manipulator" PIC for the purposes of getting your ratings. But once you have your ATP, what's the point? I don't know of a single employer who will take your PF time as PIC.

Contract 91 gigs maybe.

Also, insurance and third parties like Argus.

Never flown a GA day in my life so learned something new.
