What is Vlo and what does it control?

Vlo is the landing gear operating speed. It’s the maximum airspeed at which you may safely extend or retract the landing gear. If you try to move the gears above this speed, the hydraulic system and gear mechanism may not handle the loads, doors may not open or close properly, and the gear could fail to extend or lock or retract fully. So you must stay below this limit whenever you plan to move the gear. It’s not about stall speed with the gear down, and it’s not limited to extending or retracting alone—the limit applies to both operations. (There’s a separate limit, Vle, for the maximum speed with the gear down.)
