to log SIC in the citation, u'd have to hold appropriate category and class rating on your FAA CPL/instrument licence. This would be the same as P2 in CAA countries. To log it as P1/US as per CAA rules, u'd have to be type rated in the citation and "agree" with the PIC to countersign ur lb. If u r typrated in the citation, u have the luxury of accumulating PIC jet time, otherwise it will all be SIC time. I remember that from my pt 135 class.
