Emergency extension of the Nose landing gear is accomplished by which system?

• A. Auxiliary hydraulic system
• B. Electrical hydraulic system
• C. Pneumatic system
• D. Mechanical system

Answer: (A)

Emergency extension relies on a backup power source that can operate the landing gear even if the main hydraulics fail. The nose landing gear is moved by hydraulic pressure, so having a separate auxiliary hydraulic system specifically for emergency extension provides the necessary pressure without depending on the primary hydraulic circuit. This system has its own pump and reservoir and is designed to deploy and lock the gear reliably under failure conditions, which is why it is the chosen method. The other options don’t offer the same guaranteed, independent hydraulic power for gear deployment: pneumatic systems don’t supply enough controlled force for gear actuation, and a purely mechanical backup is not the standard for modern nose-gear emergency extension.
