While we are on the subject, I remain confused about when a ground
instructor certificate is needed. As a CFIG could I legally teach a Private
Pilot SEL course or would I need to first get a Ground Instructor certificate?

I hold GI, AGI, and IGI certificates. I took the tests beacause I had
studied all the required material for the flight instructor ratings. I
don't expect them to be useful unless I fail to keep my CFI rating
current. I know of nothing a ground instructor can do that a flight
instructor with equivalent rating cannnot.

I hope it's not possible to get a sport pilot instructor rating for a
type of aircraft you are not rated in. Surely the regs are not that
stupid.
