The other question referencing turbojet-greater-than-12500 lbs speaks to the requirements for getting a initial turbojet type rating in a level "C" simulator. Atlas has hired t-prop-only pilots, but got them SIC-only B744 types, and then had to deal with pairing requirements, as they could only occupy the right seat. When they acquire "X" hours in type on the line, that allowed them to then go in for the full type rating and release to normal scheduling. (a practice from tough-to-find-qualified-pilots periods e.g. "when everybody's hiring").

I believe with a level "D" simulator all of this is unnecessary.

I may be wrong.
