The present sytem is the pre-cursor of the NASA evaluation of the Turbulence prediction & warning system TPAWS.
The TPAWS technology is an enhanced turbulence detection radar system that detects atmospheric turbulence by measuring the motions of the moisture in the air. Researchers have already tested TPAWS on a NASA Boeing 757 research aircraft. The TPAWS equipped plane searched for turbulence activity around thunderstorms for eight weeks. The aircraft flew within a safe distance of storms, so researchers could experience the turbulence and compare the radar prediction to how the plane responded to the encounters. After one severe patch of turbulence, a NASA research pilot said his confidence in the enhanced radar had "gone up dramatically," since the plane's weather radar did not show anything, while the same time the TPAWS display showed rough skies ahead.
This evaluation started in 2004 and I do not possess any current data but would imagine it is already in production for new aircraft. Your radar could well be the latest with TPAWS. My last experience of Wx Radar on the Classics only had WX or Map capability.
