Rudder Travel Limit Fault
Just to give a little information on the subject (A330) of the rudder :
Rudder : Yaw damping in turbulence after failure :in case of a total loss of electrical power there remains a backup yaw damper unit completely independant (it has its own gyrometer and the electrical supply is provided by generators driven by two of the hydraulic systems.
Rudder deflection : controlled by 2 limiter channels and two SECs. If both calculators fail, the max rudder deflection available remains what it was before the failure ; that is 4 degrees in cruise. The max deflection will become available again when slats are extended.
