I hold an AGI certificate that I haven't exercised the privileges for in quite some time (more than 12 calendar months).
According to 14 CFR 61.217, can I simply take a Flight Instructor Refresher Course (online or in person) and restore my privileges?
§ 61.217 Recent experience requirements. The holder of a ground instructor certificate may not perform the duties of a ground instructor unless the person can show that one of the following occurred during the preceding 12 calendar months:
(a) Employment or activity as a ground instructor giving pilot, flight instructor, or ground instructor training;
(b) Employment or activity as a flight instructor giving pilot, flight instructor, or ground instructor ground or flight training;
(c) Completion of an approved flight instructor refresher course and receipt of a graduation certificate for that course; or
(d) An endorsement from an authorized instructor certifying that the person has demonstrated knowledge in the subject areas prescribed under § 61.213(a)(3) and (a)(4), as appropriate.
It appears so, but I guess at the root of my question is, is it really that simple or did I miss a regulation or sign-off requirement somewhere (I know I could get signed off in leiu of the FIRC).
Then to keep current, what constitutes activity as a ground instructor giving pilot...training
? Just teaching and logging that I've been teaching ground school, or would I actually have had to endorse some people to take the written exam during those 12 calendar months?
