1. Where is the yaw damper on the MD11 exactly located?
2. What and how does the dual rudder work?
3. Does the MD11 have trim tabs on the rudder?
The yaw damper is a function of the FCC's, fly by wire as to say but seperate from a/p function. It was more or less the inspiration for LSAS on the 10 but functional on the 11.
The dual rudder is a redundantly powered system that mechanicaly deflects the trailing edge of the rudder's in more deflection.
