FWIW...Thats not what I experienced. I was an Instructor/Evaluator in the C21 (LearJet 35), KC135 (military version of the B707) and the KC-10, and when I went to get my Instructor comp, they gave me the MEI/MEII. When I asked about the CFI,, she told me because I did not instruct in single engine, I would not be getting the CFI. I did say I have many hours in the Lear flying simulated single engine and 10 minutes actual single engine after an engine loss on takeoff,, she chucked and said it didnt count.
