I suppose the source of my confusion is that there are situations in which you would log dual given and SIC. But, dual given can then later be interpreted as PIC time.
Also, would you only log dual given for OE? What about for line checks? Or say you're in the jumpseat giving instruction for a special airport qual... you obviously can't log flight time, but would you log dual given?
When it comes down to it, airlineapps has got me confused!
