Sandel Avionics’ HeliTAWS terrain warning and avoidance technology, introduced at last year’s Heli-Expo, has been adopted for inclusion in Rockwell Collins’ line of integrated rotorcraft avionics systems under a long-term software license agreement between the companies.

Sandel’s proprietary TrueAlert adaptive algorithms are at the heart of technology that Gerry Block, the Vista, Calif., company’s founder and CEO, says virtually eliminates nuisance alerting in low-level helicopter flight. He noted, “I’m pleased that Rockwell Collins has chosen our HeliTAWS as a platform to enhance the safety of its customers’ rotorcraft.”

The original Sandel ST3400H HeliTAWS product is a panel-mounted display with integral processor that combines the terrain database, radar altimeter, GPS and air data information to present the pilot with a color-coded map of the helicopter’s immediate environs and its present and predicted flight path. The 3-ATI unit is a direct form, fit and function replacement for a radar altitude indicator.

Sandel Avionics is demonstrating the ST3400H at Booth No. 3518.
