Nothing. There is no AOA protection outside of normal law.
PFD and speed scale changes to indicate this.
There is a stall warning based on AOA (if the plane thinks it has a valid AOA), but nothing else protecting AOA.
So the PF with less than a year experience in the Airbus used full nose up SS with this knowledge???? Did he forget? Why did both pilots use full up pitch control if they knew they had no stall protection? All us conventional airline pilots know exactly what would happen. Exactly what their profile did putting them in a deep stall.
The initial report left all the important stuff out like if they pulled up and with frozen pitot tubes and static pressure dropping did they get an erroneous overspeed warning.
They must have a reason to keep this quiet but eventually they will have to tell us what really happened up there.
