CFI renewal
Evening Gents!
Does any checkride with the FAA automatically renew your CFI-ticket or do you have to take a refresher every two years?
I know about the signing off so many students, and having this and that pass-rate, but not working as instructor it doesn't apply to this case.
Just want to keep my CFI current.
Could I renew by adding an FAA ATP single-engine for example?
