I've done 3 planes now at RAH. (CRJ, 145) S5 170 was by far the most straight forward experience I have had yet. On day 1 of indoc you'll get a binder with a study guide. Know the study guide. If it's not bolded in the POH you don't have to have it memorized. There are not enough memory items to really waste your time studying before hand. so many are the same. Limitations you'll spend 2 hours maybe and have down. I would use my time before class to make sure my house is in order and see my family. Unless you live in IND or STL, plan on being gone the better part of 3 months.
