It's a strip they use for detecting ice buildup on the wings.. Essentially, what they will do is run a pole on the strip (which has a rough surface like sandpaper), and if the pole ran smooth over the strip, there was ice on the wing, and the aircraft needs to be deiced.

Srbmod is right.

I've started to notice them on the leading edges of some UA 737's, but the strip does not continue across width of wing such as TWA's.

Interesting - DIA

Pls forgive if this is a stupid question, but the "rough like sandpaper" sounds like it would create drag, maybe not much but over the course of a year or so, enough for bean counters to notice.

Obviously if the airlines are doing this, it doesn't,
But can some knowledgable persons explain a bit about this?
