Ok, So lets say you know a guy that flys a Citation II for his business. He has a type rating in the CII and a Single Pilot wavier. So this guy can fly his Citation around all by himself, but gets bored from time to time and asked you to accompany him on some trips. Say you also have a Commercial / Multi / IFR ticket, can you log SIC with this guy when you fly, and what would an SIC Type give you in this situation?
