as an example, here's what Southwest says about PIC time ...
Flight Experience:
2,500 hours total or 1,500 hours turbine total. Additionally, a minimum of 1,000 hours in Turbine aircraft as the Pilot in command3, as defined below is required. Southwest considers only Pilot time in fixed wing aircraft. This specifically excludes simulator, helicopter, WSO, RIO, FE, NAV, EWO etc. NO other time is counted.
Southwest Airlines defines "Pilot in Command" for the purposes of application for employment as the Pilot ultimately responsible for the operation and safety of the aircraft during flight. The Pilot in Command should also be the Pilot who signed for the aircraft and who is the ultimate authority for the operation of that flight. For military personnel, Southwest Airlines will allow flight time logged as "Pilot In Command" (PIC) only if you are the Captain/Aircraft Commander, Evaluator, or Instructor Pilot. Primary time will only be considered PIC on a specific aircraft after an individual upgrades to Aircraft Commander in the appropriate aircraft. Time logged, as "Other Time" will not be considered.

I realize that this is the way it is but it chaps my ass to no end. Of all the above listed activities the helo pilot is the only one actually flying, it is not all that different. A PIC of a cargo or patrol plane can get hours and hours of PIC time when they are not even in the cockpit at the time, I realize that they are ultimately responsible for the aircraft but I dont understand the anti helo bias. Not all arilines fall into this thought process but oh well.
To answer the previous question on FCFs, the Cobra is per OPNAV single piloted so most squadrons groups have SOPs that state only the FCP will be at the controls. I have flown entire missions from the front where the only time I took the controls is to land in a FARP. The industry standard is to split the flight time with the AHC getting the high end of an unbalanced split.
