If hydraulic systems 2 and 3 are lost, what happens to Nose Gear extension?

• A. Nose Gear will NOT extend
• B. Nose Gear extends normally
• C. Nose Gear extends using a manual override
• D. Nose Gear remains in place

Answer: (A)

The nose gear extension relies on hydraulic pressure from specific hydraulic systems. If both hydraulic systems 2 and 3 are lost, there is no hydraulic power available to drive the mechanism that lowers and locks the nose gear. Without that actuation pressure, the nose gear cannot extend, so it remains in the retracted position. In this scenario there isn’t an alternate extension path that would deploy the gear, so the gear will not extend.
