B737NG rudder pressure reducer 1 eng
 

In normal operation the rudder pressure reducer reduces the rudder pressure when accelerating through approximately 135 kias.

How much is the pressure reduced?

Is there any change in this speed or pressure if flying a 1 engine approach?

thanks,
do you know anything about the output pressure in the engine out case?

The B737NG Rudder Authority Limiter doesn't make any adjusments for an engine out situation. The SMYDs (Stall Mgmt Yaw Damper Computers) use N1 inputs, but they are for BITE entry purposes.
