What is the purpose of the emergency extension?

• A. Unlocks the landing gear up lock mechanisms and aids in the landing gear down lock.
• B. Locks the landing gear in up position.
• C. Activates nose wheel steering.
• D. Opens the landing gear doors to reduce drag.

Answer: (A)

The emergency extension is meant to get the landing gear down when normal hydraulics are not available. Its main function is to unlock the gear’s up-locks so the gear can move from the retracted position toward the down position, and it helps the down-locks engage to secure the gear for landing. This ensures a safe, locked configuration even in an emergency.

It doesn’t describe locking the gear in the up position, and the nose wheel steering and its controls are separate systems not activated by the emergency extension. It’s also not primarily about opening doors to reduce drag—the doors may move as part of the extension process, but the core purpose is enabling deployment and proper down-lock engagement.
