What is the landing gear extension/retraction speed (Vlo) for the PC-12 NGX?

• A. 180 knots
• B. 100 knots
• C. 170 knots
• D. 200 knots

Answer: (A)

Vlo is the maximum speed at which you may extend or retract the landing gear without risking damage to the gear system or the airframe. For the PC-12 NGX, this limit is established so that gear operations occur within the safe mechanical and hydraulic envelope, ensuring reliable gear cycling while preserving control of the airplane. The correct option matches the aircraft’s published Vlo in the official documentation, so using that value keeps gear extension or retraction well within the safe operating bounds. Values above this limit would exceed what the gear system is designed to handle and could lead to gear or door damage, while values far below the limit would unnecessarily constrain operations and complicate procedures. Always verify the exact figure in the POH or the placards for your specific airplane.
