What is the effect on rudder control when the flight control disconnect handle is used?

• A. It isolates rudder from both sides
• B. It doubles rudder authority
• C. It does nothing to rudder control
• D. It locks rudder in the center

Answer: (C)

The flight control disconnect handle is used to separate the primary flight control surfaces from the normal control path so the system can be isolated for manual control or maintenance. This action does not alter the rudder’s behavior because the rudder has its own dedicated control path and hydraulic/actuator setup that remains independent of the disconnect mechanism. Therefore, pulling the handle does not change rudder authority or lock it; rudder input from the pedals continues to function as usual, assuming hydraulic power is available.
