We installed accelerometers on most of our airplanes where it measures turbulence. It gets uplinked to a magic brain somewhere in the CONUS. Gets processed along with altitude, lat/long/speed, intensitity, aircraft type, mixed together with forecast modeling, then uplinked to the Surface EFB devices around the world graphically, both laterally and vertically Then it's "predictive" because it knows your current flight plan, where you are and where you're going.
Pretty cool stuff.
I'll try to snag a photo of it.
