Post What are those vertical metal tabs on top of wings?
I see them on most wings. On top behind the leading edge, about 2 cm high and 10 cm long running front to back, and spaced horizontally about 1/2 meter.

I guess it is a visual gauge to eyeball ice buildup. No way can something that little have an aerodynamic function.

Thanks for reading my question.
