After a 20 year break in flying I've decided to reinstate my CFI. I have it scheduled with an examiner August 1. I did a reinstatement in the late 80's with the FAA & after the inspector saw my TT as an instructor, we had a brief oral exam, & then flew for 40 minutes or so with me in the right seat. It was very easy. I'm a little more intimidated this time since it's been 20 years & it's an examiner rather than the FAA. I'll be taking the check ride in my newly acquired 182. I guess my questions are two-fold. Will it be a big deal? What should I focus my study on? I feel pretty current with airspace & parts 61 & 91. Anyone here gone through this recently? Thanks in advance.
