Don't look at your dad's FMC stuff! They're different boxes. Better to not clutter yourself up and have "contamination" issues...

If you want to buy something to study, purchase the AvSoft CRJ Quick Study Guide... It's a lights and switches "button book" that tells you what does what and when for the cockpit and other systems. It's simply the best oral prep guide that I've found.

But really, you don't need anything (like others said). If you can get a copy of the memory items and limitations from a CURRENT AWAC pilot, that would probably be the best stuff to look at and get memorized before you start training.
