I would hazard a guess that the stall protection will be based on alpha provided by the AoA vanes to the Adirs.The QRH states that with a triple ADIRS failure stall warning is lost.The QRH continues by requiring use of the standby altimeter/ASI but if these are unreliable as well you are rapidly into unreliable airspeed territory which the x-list fails to mention!This x-list does appear next in the QRH.
The x-list for unreliable airspeed is quite long and initially requires a number of memory items.Pitch and power settings for level flight do not appear until the fourth page.
Did anybody else notice the sim in the BBC programme was an A320?
