The operation of the device shown in the illustration is dependent upon __________. GS-0116

Correct Answer: Option B — all items, similar to "N" move as the rudder stock rotates

The vane-type steering actuator operates by the movement of internal vanes against the housing. These vanes, identified as item N, are mechanically fixed to the rudder stock. As the rudder stock rotates, the vanes must move in unison to displace hydraulic fluid and generate the necessary steering torque.
