[QUOTE] [PS. The Airbus does not have a yaw damper. It has a FAC that contains yaw damping functionality, but the FAC sends commands to the Rudder Hydraulics based on what it understands is going on../QUOTE] Not true at all. Airbus definitely has yaw dampers which work on G and Y hydraulics. If you loose G+Y you have FAC but loose yaw damping. Check FCOM Flt Ctl reconfiguration.
