OG,
Interesting post...
I am currently working with the real-time wake turbulence measurements, so I understand the roll-up, creation, advection, and decay of the vorticies, and the effect of winglets and sharklets quite well. (crunching data on hundreds of multi-variant arrivals, incl A380)
Would be interesting to converse on these matters, especially in regards to wingtip vorticies.
