Taking weather radar to the next level

In addition to detecting and assessing storm systems, the Enhanced Turbulence (E-Turb) feature of Rockwell Collins MultiScan Hazard Detection system detects light to moderate turbulence events and provides flight crew warnings up to 40 n.m. ahead of the aircraft. Speckled magenta areas on the radar screen will indicate light to mild turbulence and solid magenta areas identify regions of moderate or greater turbulence.

E-Turb functionality incorporates technology developed by AeroTech Research (USA), Inc. and was made possible through a 2004 contract with NASA in which Rockwell Collins and AeroTech Research successfully integrated and evaluated the E-Turb feature on a commercial airliner.
