Hello Talon
An SIC type is something that was put in place in the US for the airlines to get away with meeting ICAO international standards that dictated that both crew members needed to be typed, so the FAA came up with the cheaper alternative of the SIC type but most airlines abroad (if not all) issue full command type ratings to all their crew members since their CAA's don't recognize the SIC type, that is why they require a command type rating because the JCAB will issue the license validation based on that. Sorry but a command type rating is required.
Now back to the regular programming.
