But SWA's website says this...
I know this has gone around and around on this board, but SWA's own website is pretty clear about it.
Southwest Airlines defines "Pilot in Command" as the Pilot responsible for the operation and safety of the aircraft during flight. This definition is taken from PART I of the FAR. Southwest Airlines further allows logging of PIC as follows: For an aircraft requiring a type rating: If both pilots are type rated, the pilot in the left seat and sole manipulator of the controls may log PIC. If only one pilot is type rated only that pilot may log PIC, regardless of seat position. For aircraft not requiring a type rating: Only the pilot in the left seat and sole manipulator of the controls may log PIC. For military personnel, Southwest Airlines will allow flight time logged as "Pilot In Command" (PIC) only if you are the Captain/Aircraft Commander 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. When converting taxi time a conversion factor of .3 or eighteen minutes, per leg/sortie should be used. These guidelines are imposed by Southwest Airlines for the purpose of standardizing the calculation of flight time.
Maybe you are at a Part 135 Carrier and either fly the empty legs Part 91 or have co-captains....?? Why read more into it than what SWA's website says specifically? I'm sure someone will say "they spoke to so and so at the AIRINC conf. and they said to do it this way or that way". Seems clear above.
