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.
Actually, there's no magic involved - just simple aerodynamics. Any given wing will stall at 'X' degrees AoA and that is all there is to it. In the case of an iced-up wing, the AoA at which it will stall is different to that of the same wing with no ice - because the aerodynamic shape of the wing has been changed by the ice.

All the stuff you mention about manouvre loads and weight are irrelevant - they may well alter the aircraft's AoA for any given flight condition, but the wing will always stall at the same AoA. And the elevator is your AoA control.

If you fly aeros, you ignore IAS as far as departure is concerned, You fly AoA.
