Therefore, I have always thought the reason Vle is higher than Vlo is because the landing gear and/or gear doors are certified to withstand a higher speed while stationary (extended) than when in motion (extending or retracting).

Anybody agree or disagree?
All the planes I fly have the same speed for Vlo (extension) and Vle. Still flying light twins, Arrows, etc., but otherwise, I agree.

I agree with Brendan. Vlo can have 2 different speeds, one for extension and one for retraction. Vle is the max speed with the gear hanging out and locked, not moving.
I don't know B-777 speeds, but in the EMB145 Vlo-extension is 250, Vlo-retraction is 200 and Vle is 250.
