Logging PIC on a multi-crew flight (U.S.A.)

[Seminole27p]

Hi again folks,

On a flight with 2 captains and 2 fo's, can both captains log PIC time for the entire flight? can I, as the junior captain log PIC for the entire flight? or can I only log PIC the time I am sitting at the controls?

I am trying to do my US logbook and in the country where I fly (Colombia) the regulation allows you to log the entire flight as PIC, whether or not you're the controls i.e. sleeping, etc.

Thanks,
