109 slots

Which is why you'll see some photos of 109's on the ground with slats retracted, and some with slats extended. If they were spring driven, the slats would always be extended on the ground, wouldn't they?

I agree with your theory, like I said, I'm no 109 expert. However I am familiar with pure aerodynamic slats. I saw a french design during my training that was easily pushable to either retracted or open, like you say about the 109.

I just believe that, for maintenance purposes and wearing, there should be some spring to "dampen" the movement of the slats so that they don't violently slam open or shut. Anyone could tell you that this will fatigue the design unless there was some buffer or spring to soften the movement. Anyways, there seems to be no springs forcing the slats to open.

By all accounts the109 slats actually did, on occasion, violently slam open and shut.

Well it is really funny but i didnt see in any screenshot or videos from BoB slats in 109 or 110. I watched all screenshots from 2008 until now and i didnt saw any open slats in these planes even in turns, take off etc.

It start to be funny

I can hear those damned air-pressure slats laughing at all of us, in the voice of Vincent Price. Time for an accurate screenshot from Mother Russia? "пожалуйста" = "please".
