As I mentioned above, I did two typeratings in a level D sim. Both typeratings were on my license before I flew the actual aircraft
Presumably not in JAR-land for heavy twins then, since JAA / EASA requires at least 2 hrs aircraft time before the type rating course is complete. So whilst you can do the LST with only the Sim time, you can't actually complete the course and hence get it on your licence without the real aircraft time.
