Lapsed Advanced Ground Instructor certificate, can I take a FIRC and and restore my privileges?

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?

• As a general rule, there's no need to look for extra requirements that aren't stated in the regulations. Hah! Yeah, that is for sure, its more that this one just seemed too straight-forward. Jun 12, 2018 at 17:27
