Hey all. I was looking at this photo:

and I noticed what looked like ailerons on the trailing edge of the winglet. Any idea how they are used? I would think they would be too close to the CG to really have any effectiveness as additional rudders, but maybe I'm wrong.

Thanks as always.

No, its not a moviable flight control on the winglet. It's just a panel line.

Sorry but why would you think that's an aileron? If you know what CG is then you should have some comon sense. Plus ailerons and rudders are not the same.

Right. Panels on the CRJ must also be sealed. We use a black sealant at my company, hence the thick, black line that you see.

Alright buddy, take it easy there. Thank you for inferring that I have some common sense. Now please realize that its proximity to the CG was the exact reason for my post. It looked like a control surface to me, and I was confused as to why there would be a vertical control surface at this location. Sorry if I confused you by saying aileron - I don't know what a control surface on a winglet is called.

We're all here to learn. No need to discourage questions  

Thanks guys.

Good Observation.
Def a panel line sealed with Sealant.Maybe additional Paint should have been applied over it.
