220 kt: Max speed at which landing gear may be retracted (VLO retraction).

220 kt: Max speed at which landing gear may be retracted (VLO retraction).

• A. VLO extension
• B. VLO retraction
• C. VLE
• D. VMO

Answer: (B)

Understanding landing gear limits: there are separate speed restrictions for extending and retracting the gear, plus a general gear-extended limit and a broader operating limit. VLO retraction is the maximum airspeed at which you may safely retract the landing gear. Going faster than this can prevent the gears from retracting properly or damage gear components or doors due to aerodynamic loads. That’s why 220 kt is the value for VLO retraction. The other figures refer to other situations: VLO extension is the limit for extending the gear, VLE is the limit when the gear is still extended in flight, and VMO is the overall maximum operating speed of the airplane.
