I'm still baffled.... why 'blame' the AoA vane?
Because what was discussed is the part following the actual aerodynamic stall, where the ice has melted away, indicated airspeed was realistically measured to be below 60 kt and AoA exceeded 45°. Someone with not much knowledge about basic aerodynamics or flying dug out the certification requirement that stall warning should sound as long as the aeroplane is stalled, took umbrage at Airbus' decision to use 60kt instead of WoW to invalidate AoA measurements, thereby cutting off the stall warning and here we are. One step short of insisting that X-31 style probe should be installed on all airliners.
