I had a quick question regarding the CFI. Once I go through the fast track program and obtain all my ratings, as a CFI am I only allowed to instruct single engines for ATP students? Does the CFI include CFII and MEI? Sorry if this question makes no sense, I am still learning about all the different ratings.
Also, does ATP hire CFIs/CFII/MEIs outside of their program or do they strictly hire from within? If so, what are the requirements for outside contracted instructors? Thank you very much for answering my questions again.
