Which hydraulic system controls the nosewheel steering?

Explanation:
Nosewheel steering is driven by hydraulic power, not by electrical power. The pilot’s input from the tiller or rudder pedals is processed to move a hydraulic actuator that turns the nose gear. In the typical three-hystem configuration used for several aircraft, the steering circuit is supplied by Hydraulic System 2. This separation keeps steering control independent from the other hydraulically powered systems and provides the necessary force and responsiveness for precise ground handling. The other hydraulic systems power different subsystems (such as main flight controls, landing gear mechanisms, or brakes), so they aren’t used to control nosewheel steering. The electrical system isn’t the source for this actuator, since hydraulics provide the required torque and reliability for steering the nose gear. So, the hydraulic system that controls nosewheel steering is System 2.
