REFLECTOR: Gap Seals, fences, zig-zag tape

[Brett Ferrell]

I heard an explanation once, I think it was from Klaus, and my recollection is it's because with the spanwise flow corrected, the wing generates lift more efficiently, and thus can fly slightly faster at the same angle-of-attack, or similarly climb better.  Of course, I could be butchering it too, but that's what I recall.  When we get back in the air I plan to to some oil and performance testing on fences and vgs and turbulator tape, hopefully fairly rigorously.

> Good question. From what I have seen, there is no span-wise under the wing, although I don't know about out board of the aileron. I also don't see how a fence on the out board end of the aileron would affect aileron effectiveness; so I'm guessing the any improvement in climb rate would come from fences out-board of the aileron. Maybe Klaus could explain that I'm wrong.
