All a/c have an angle of attack indicator. It's called the stick/column and when its aft of a point which you can paint on the fus, the wing will be stalled. Don't bother quoting different flap positions etc because it always works out more or less to the same spot. For example if you are tightening a final turn, be very aware of stick position!
Ha! Didn't take long! As I said in post #22:
Soon some bright spark will mention 'stick position'.
Camarque: No, of course one isn't fixated on any instrument in aeros, but one would take occasional glances as one does with the other instruments to confirm that at this speed and this 'G' the AoA isn't too near the top of the yellow arc. In a sustained pull (max performance 360 for instance) one can pull to the limit!
