Collins' now provides a turbulence-detecting option in its WXR-700 Doppler Weather Radar. Shown is the cockpit display which presents more than just an indication of different rainfall rates. Using a proprietary Doppler-processing technique, changes in the velocity of weather-produced particles relative to other particles can be measured. Thus, turbulence is shown here in magenta within an area of light rainfall -- where a pilot might not otherwise expect it. U.S. FAA approval was given to the system in late February.
