What is the maximum gear retraction speed (VLO)?

• A. 250 KIAS
• B. 220 KIAS
• C. 270 KIAS
• D. 235 KIAS

Answer: (A)

VLO is the speed at which the landing gear can be safely retracted. This limit is set by the gear’s mechanical and hydraulic design, including the doors and actuators, to ensure the gear fully stows without risking damage from aerodynamic loads or door interference. In many aircraft, that retraction limit is 250 KIAS. Staying below this speed guarantees the gear can complete the retraction cycle reliably and with the doors fully closed. Exceeding VLO can lead to incomplete retraction or gear/door damage, so pilots are trained to extend or retract gear only up to this speed or below. The other numbers represent either different limits for other conditions (like gear extended) or model-specific values, but 250 KIAS is the typical retraction limit.
