Landing Gear And Brakes Practice Test

What is the maximum gear extension speed (VLO)?

250 KIAS 260 KIAS 240 KIAS 230 KIAS

Correct Answer:

250 KIAS

Explanation:

VLO is the maximum speed at which the landing gear can be extended or retracted safely. Going above this speed means the gear and doors are subjected to higher aerodynamic and inertial loads, which can prevent proper extension/locking or even cause mechanical damage. So you extend or retract the gear only at or below this limit and complete the operation within that envelope. For many airliners, the published value of VLO is 250 KIAS, which is why 250 KIAS is the correct choice. The other speeds either exceed the limit or do not align with the standard gear-operating speed used in typical aircraft procedures.
