Well, I finally took the plunge and am working toward at least the written portion of my CFI certificates. I already had the Fundamentals of Instructing (FOI) book from Jeppesen, however, I just picked up the Gleim study guides for the FOI and the CFI and Ground instructor written.
I had passed the FOI once, about 5 years ago, so I'm not too worried about that one. Given my almost 8-9 year absence from actually flying, I KNOW I definitely need to brush up on the basics though, in terms of FAR's, airspace, flight physics, etc.
I'm hoping to do the FOI written around March/April and the CFI written around June/July. Currently, goal is to get current as well around February/March as well. I'll definitely be posting a little more about my progress now that I've actually STARTED the process! Here's to 2012 being the year I get back in the air.
