A number of posts earlier in this discussion have mentioned that an angle of attack instrument would help the pilots make a better assessment of a possible stall condition. I noted with interest that in the AF447 final report that is readily available on the web, in section 4.2.2 it says, "Information on angle of attack is not directly accessible to pilots", and a couple of lines later, "it is essential in order to ensure flight safety to reduce the angle of attack when a stall is imminent. Only a direct readout of the angle of attack could enable crews to rapidly identify the aerodynamic situation of the aeroplane and take the actions that may be required". That seems a clear enough recommendation concerning the A330.
The A330 aircraft type involved in the AF447 accident did have, as standard, angle of attack sensors installed, but may have become blocked in the weather conditions prevailing at the time of that accident.
Does any A320 pilot here know if the situation is similar on the A320 i.e. that AoA sensors are installed, and the data available to the flight control system but not as a direct readout that the pilots have access to? Or was the fitting of AoA sensors not part of the design of the A320?
