Spitoon, all,

Really, thanks for the time and the reply....
I am sincerely asking about this, because I realize there is the criteria, that was written be PhD's in Atmospheric Science, using calculations that have little foundation in the real world, or with real aircraft.
In my experience with RNP procedure design, is that ATC is NEVER involved or consulted, hence I have quite a few RNP procedures that have been dictated and approved by regulators, that are permanently NOTAM'd out because the design is not something ATC would ever authorize...my favorite example is idle descent, oversold as saving fuel and track miles to the governments, but completely unmanageable in a blended queue.
Procedure designs where I forced regulators to include ATC input, look completely different in many ways, and make operational sense for the aircraft and ATC.

I have watched the approach/departure sequencing for LHR on Web Trak, so I have a good idea of the operations, at least for what is shown with ADSB equipped ac...

So, real time WT measurements, combined with real time ops, can be a very powerful tool to optimize operations, and provide a toolset for ATC to 'see' the wake turbulence real-time. Wake turbulence is a very complex animal, and I am hoping that once the data gets out there, it will radically influence ops, and in a very good way.
I am asking all of these questions, as I am currently working on the departure system, which is certainly different than approach configurations in many ways.
I will hazard a crude animation of what the approach system does, taking measurements every 3 seconds at 3 critical approach phase locations. (the results shown diagrammatically are center vortex, actual, from a 737-8)
The animation is at the bottom of the page... Wake Array

Again, I certainly appreciate any and all input...
