Hi everyone. I was lucky enough to visit the flightdeck while inflight on an MD
-83 of my national carrier. It was during night time, and I saw a wonderful purple set of waving flashes along the center window frame. It looked just like the small dancing lightings seen on those metal spheres surrounded by a much larger crystal sphere. The pilot was the one that got me out of my perplexness and told me they were generated by the friction with the air. Has anyone seen this?
It got me thinking, why is this static not discharged by the static wicks on the wingtips? And one other thing, is this seen on other aircraft other than the DC9/MD80/90/717 series? I refer to these because they have a center window frame that strikes the air more directly than the others and probably that is why I only saw it on the center frame. Thanks in advance
