I don’t really understand CAFlyer’s remark about “not doing this to your CFIs”. Advancing a pilot’s capabilities is what they do for a living. Anyway, I applaud Mark Phelp’s efforts to get back in the saddle of improving his skills. Mark, if the Class 3 represents a barrier for you, you might consider a Basic Med. I’ve been flying my Comanche 250 with that for several years now, and find it much easier to deal with at the age of 80.
