Reference Pace's point, I was rather incredulous to read a recent GAPAN document which firmly stated that all PPL-level flying should be about operating firmly in the middle of the envelope, and anything else about getting back there again promptly.
I think that GAPAN are, bluntly, wrong. PPLs should be happy to do steep turns, slow flight, high speed flight if they want to. And training to the corners of the envelope (but clearly, not beyond, that's test pilot territory and requires some very very specialist training) should be a normal part of PPL training.
Which doesn't detract from training concentrating upon a normal and instinctive response to high AoA conditions is to get away from it quickly, UNLESS you went there deliberately and with prior thought.
