Thanks for the link Franz, it should help more here to consider stall recovery and recognition and corrective actions.
The first graphic in the file shows the curve for a typical straight wing, large camber wing. Swept wings generally have a lower slope and an extended curve at the top of the curve. So as Franz, 'bird, Smilin' Ed and I have seen, you can fly around up at the top of the curve when you need to, but you have to be very careful!!! Besides, the plane is usually buffeting/shaking like crazy - it's telling you it doesn't like it there, duuuh?????
As PJ has noted, the mach buffet and overspeed have a different "feel" than a no-kidding aerodynamic stall. Personal opinion, but I suspect the 'bus is very tolerant of mach overspeed until maybe 0.9M or so. So get the nose down and worry about mach later.
Observation: The displays I have seen for the 'bus show a small AoA indication on the left scale. Is that correct? My preference would be a larger range and not worry about the "low" end, but the "high" end. Comments?
Edited: the main Pprune forum has this excellent link concerning stalls. I wonder if the AF447 story prompts this... Hmmmm.
