The Nosewheel Steering is powered by which hydraulic system?

• A. Utility hydraulic system
• B. Booster hydraulic system
• C. Electrical system
• D. Pneumatic system

Answer: (A)

Nosewheel steering uses hydraulic power, supplied by the utility hydraulic system. This system provides the pressure to the steering actuator in the nose gear, allowing the wheel to turn in response to the cockpit tiller input. It’s designed for the kinds of nosegear actuation tasks used during taxi and high-load steering maneuvers, balancing adequate force with reliable availability.

The booster hydraulic system is reserved for delivering higher pressure to certain primary flight-control surfaces when extra boost is needed, not for nosewheel steering. The electrical system doesn’t supply the hydraulic power for steering, and the pneumatic system handles different functions such as starting or anti-ice rather than steering actuation.
