MC / HWD - yep, accepted all of that. Just felt that there are too many people (and I believe quite a few PPLs amongst these) who have a belief in the absolute fact that a wing will stall at x deg AoA (some who I have spoken to seem to even just think that AoA is just the angle between the wing and horizontal!).
I just felt it was worth pointing out that it isn't just a magical thing that you'll stall at x degrees (where x is a constant for a particular aircraft type) and that's all there is to it - a lot of things affect what your critical AoA is for any situation.
I teach Principles of Flight to Air Cadets (a lot!) and this is the one thing that they have a genuine difficulty remembering when they go aerobatting in Tutors!
