What is the purpose of an emergency extension procedure?

• A. To extend and lock the landing gear when normal hydraulic power or control circuits fail.
• B. To retract the landing gear in case of emergency.
• C. To manually jettison the landing gear.
• D. To deploy spoilers for extra lift during emergency.

Answer: (A)

Emergency extension procedures are there to extend and lock the landing gear when the normal hydraulic power or control circuits fail. This provides a dependable path to deploy the gear so the aircraft can still land safely even in degraded system conditions. Typically, it uses an alternate or manual extension route that bypasses the failed circuits, sometimes relying on gravity, springs, or a mechanically actuated mechanism to get the gear down and the down-locks engaged. The goal isn’t to retract the gear or to jam it in the up position; it’s to ensure the gear is down and locked for a safe landing when the primary system isn’t available. Jettisoning the gear or deploying spoilers for extra lift are separate functions and not the purpose of the emergency extension procedure.
