in "normal law" you
can not fly the Bus into a stall....
AFAIK the bus CAN be also flown into a stall in Abnormal Law (a flawed Normal) where the airplane enters an unusual attitude allowing pilots to "manually" get out of it. As a consequence of the plane sensing something gone wrong, the following changes happen in the law during the recovery:
- Pitch becomes Alternate (Load Factor protection, no Autotrim)
- Roll becomes Direct (mechanical yaw control)
- No reversion to Direct after LDG Gear extension
After recovery:
- Pitch stays Alternate without protections but with Autrotim
- Roll becomes Direct
- Yaw becomes Alternate
As you may suddenly get into Abnormal at any time, I've reason to believe the FOT is referred to this condition more than Alternate, Direct and MECH BCK, where the crew is well aware the plane can stall.
