Thanks PBL. You made a complex topic understandable. I strongly suspect that if the leaked info regarding this crash turns out to be true, we will be teaching this in the sims (with their associated limits) within a few months. After AF447 (A330 into Atlantic) Airbus issued training guidance for unreliable airspeed. It seems that somotogravic illusion is an insidious killer which can catch even the most experienced and of course it's usually close to the ground.

From memory I think that SRS is limited to 18.5 degrees or 22? In AlphaFloor. Of course if it's being manually flown then it would be possible to exceed these limits ..... But AlphaFloor/AoA protection will be activated VERY soon if huge pitch is demanded. AlphaFloor tends to be associated with "low speed" but it is an autothrust protection. When I demonstrate it in the sim I show guys that you can get alpha floor at 280knots IAS quite easily.

Good discussion.
