Few Cloudy -- My suggestion to turn off the yaw damper and automatic rudder control upon entering a wake vortex [in an A300] is based on my evolving suspicion that the A300 FCS in its confusion overreacted and subsequently overstressed the fin and rudder. I suspect that this accident would not have happened if the rudder only moved in response to pilot inputs.
Certainly, if turning off the A300 yaw damper and automatic rudder control inside a wake vortex would create other hazards, I would very much like to understand how that would happen.
