What does the acronym Vlo represent in aviation terminology?

The acronym Vlo in aviation terminology refers to "Landing gear operating velocity." This term is crucial for pilots as it represents the maximum speed at which the landing gear can be safely extended or retracted. Operating the landing gear within this specified velocity ensures that the mechanical components function correctly and reduces the risk of structural damage to the aircraft. Understanding Vlo helps pilots execute safe and efficient gear operations during the crucial phases of descent and approach.

Other choices do not accurately define Vlo: "Landing gear lowered speed" implies a specific operation but does not encompass the full range of gear movement, while "Landing velocity obstructed" and "Velocity limit over airspeed" do not align with standard terminology and do not apply to the mechanics of landing gear operation.
