Yeah, this was for the first 767 FOs transitioning to the 747, so I assume they could leave all the HR stuff out. Took them more than a week after the type ride to finish up.

767 initial was 7 weeks for me 3.5 years ago, and that was tight. The first time we had more than 1 day off was just prior to the Oral. There was a 747 class at the time that started before us and finished weeks after. (They had 10 days off for Thanksgiving, we had one)

Thing is - it doesn't really matter how long it took another class, just how long it takes yours. Holidays can complicate things, sims can break, but the basic footprint is right at 8 weeks or so.

As with all things Atlas, YMMV.
