Which system powers the emergency extension of the Nose landing gear?

• A. Auxiliary Hydraulic System
• B. Electrical System
• C. Pneumatic System
• D. Fuel System

Answer: (A)

Emergency nose gear extension is powered by the auxiliary hydraulic system because gear deployment requires high force and precise control that hydraulic actuators provide. If the main hydraulic system is unavailable, the auxiliary system supplies pressurized fluid (often from its own pump and stored in an accumulator) to extend and position the nose gear and engage the locks. Electrical power alone can’t deliver the necessary force, and the pneumatic system isn’t used for this task, while the fuel system has no role in gear deployment. This backup hydraulic setup ensures the aircraft can extend the nose gear for a safe landing even in a primary system failure.
