stillin 1, it is true that our rubbishy elastic powered amateur death machines don't have alpha-ometers or whatever they are properly called, but surely it's still relevant for instructors to tell PPL studes about AofA. I recall that my instructors went on about AofA a great deal and told me not to get fixated with the idea that the aircraft will always stall at speed x or sometimes at speed y, or only when going slowly, or only when the nose is pointing up. I read "Stick and Rudder" and "See How it Flies" at the time, which further shoved the "angle of attack is, er, quite important, really" point home.
