A/THR OFF
Autothrust Shut off for safety, result loss of 2 Valid Air Data Channels.
This prevents faulty Air Data from affecting Autothrust into making the wrong actions.
Because of the Airbus A/T design, the thrust would have gone to full power. A fundamental design flaw, imho, and one that will never be admitted to by Airbus. I hated the T/L not moving design of the Airbus. It works fine when all is going smoothly. But in the failure case, and non standard configuration case it causes more trouble than it is worth. It is so difficult to work out what it is or is not doing under high workload situations. Very often all you have to go on is the "cyan arc." a tiny blue trend line. Miss that and chaos can ensue.
With all the warnings and the chaos on the flight deck, it is doubtful if the FO hd the spare capacity to even notice the AT going to full power. That would have instantly de-stabilised the aircraft. Making a bad situation far worse.
