Flight surfaces/controls reaction in turbulence

Have you ever noticed the flight surfaces, and thus the yoke, are deflected a considerable amount by turbulence, especially upwards/downwards gusts, of course assuming you not resist holding the yoke in place firmly?

I expect to be same changes in feel/pressure, but to deflect the yoke considerable? How have you experienced?

I use to fly in pretty good weather and I haven’t notice the yoke to want to deflect on its own if I let it free when the wing is hitted by a gust or so. But I think it depends a lot on gust intensity, thus I don’t use to fly in bad weather, I think this is the reason I haven’t noticed it.

I figure out when the wing encounters a draft the ailerons might cancel each other the opposite deflection due to inertia, but what about the elevator? There’s nothing to cancel it out in this case. Or even in the aileron case, is the inertia too low to notice a considerable deflection?

Thanks!

If the plane were sitting on the ground and a gust of wind hit it, you would see the same type of reaction. The elevators will move first. The ailerons will move if the wind is not direct.

Ok, but inflight there is another environment, we have laminar flow, relative wind usually from the nose, we have updrafts, so how does it come there?

No I've never seen this happen. I've flown a considerable amount of light to moderate turbulent flights in both glider and powered and don't see what you are asking about in either my fat winged C180 or my thin winged DG-600 laminar flow hot rod glider at either slow flight or red line or anywhere in between.

Be aware that this guy is posting on just about every board out there, EAA, VAF, Supercub, among others, with mostly the same inane questions and non-responsive answers. He's a waste of time.
