There may be a catch to the whole counting SIC time towards PIC time for ATP requirements. Where I work, Mesaba, the SIC credit is not allowed (because Mesaba does not "participate" in the program as they say). The company and the Feds have fought over this numerous times and it's a complete Catch-22. I don't know why, but it is and it clearly states it in the regs. Perhaps it has to do with insurance policies. Bottomline, check with every major head in your training dept and APDs before you upgrade.
