Most airline applications specify that total SIC time + total PIC time = Total time. In addition SEL + MEL time should equal total time.

I suggest you log Sim time only in the Sim column of your logbook and not add it to any other category (such as instrument, Sic, Pic, night time etc...).

If you add sim time to any category other than Sim you will not be able to total your flight time tables in job applications. They are required to total up and down as well as left to right.
