Did the RTL go fault due to lack of reliable IAS? Does the Rudder become functionally unavailable at lower speeds, then? Would that have any effect on recovery from roll, or Yaw in upset??
The Rudder was limited to 7.9 degrees sweep all the way to the Ocean, per BEA report. Is that a mechanical condition that may need to be addressed post 447?
At some point in the descent, would you have selected slats to release the Rudder? At what airspeed would the slats have been susceptible to separation?
Would slats have hindered recovery?
If too fast, and Rudder was needed, would you have selected spoilers?
Rhetorically, would Protections have limited any of the other controls?
