Indoc is 2 weeks. Then you go to the sims. Time in between will vary depending on the airplane you were assigned and how busy they are. Since the first group has yet to go through this, anyone's guess is as good as any. In the past, I've heard of guys waiting anywhere from less than a week to two months between indoc and sims.

Indoc classes have averaged around 30 per class. I was in one of the two classes in 2008 that had 50 and they acknowledged that was too big. Too much to cover in too little time with so many people. I doubt you'll see another class with more than 30 or so.
