Speedbrake handle extension on ground

[Rodeo]

I saw:

…but aren't these type of limitations (maximum speedbrake extension on ground) implemented electronically? Here, the speedbrake handle itself seems stuck at 50%, as though there is some kind of hardware limitation preventing going past it -- is actually limited this way in the real aircraft?

I am told Yes.

Actually it seems I was able to fully move the handle once engines were started. Very intriguing… anyway, as long as it works

Yes it requires hydraulics.

Ah, that makes sense, thanks
