Sandel HeliTAWS™ Receives Part 29 Approval on Bell 412EP

Posted Monday, June 27 2011 as Company News

Sandel Avionics has announced it has received an FAA Supplemental Type Certificate (STC) for its ST3400H HeliTAWS™ wire and terrain safety system on a Bell 412EP helicopter. This announcement supplements an agreement Sandel has with the FAA designating Part 27 and Part 29 helicopters operating under Part 91 or Part 135 rules as candidates for Field Approval installation of the ST3400H HeliTAWS unit, providing for simplified installation under the guidelines in FSAW 02-03A. The new STC SR02355LA is available on the Sandel website at no charge with the purchase of qualifying HeliTAWS equipment.

Sandel’s HeliTAWS is a 3-ATI wire and terrain safety system that incorporates the revolutionary WireWatch™ wire-strike avoidance feature, a Sandel invention that protects helicopters from the nearly invisible threat of known wires, guy lines and transmission lines. HeliTAWS also includes Sandel’s proprietary TrueAlert™ technology, which eliminates nuisance alerts, a problem that other HTAWS products have not been able to overcome. With TrueAlert, pilots can safely take off, cruise, hover and land at off-airport locations without triggering nuisance alerts, while still receiving the established benefits of Class-A terrain and obstacle warnings during the entire flight. The system is completely automatic and does not require pilot management of the phase of flight.

Other benefits of HeliTAWS include its off-airport landing capability; high-resolution 3-D terrain display; Class A HTAWS functionality; and available NVIS compatibility. Designed for all helicopter operations, HeliTAWS is ideally suited for such demanding missions as HEMS, oil rig operations, tactical military support, airborne law enforcement, fire fighting and search & rescue.

Sandel Avionics, located in Vista, California, is a privately held company that provides compact integrated display systems for business aviation, air transport and regional, and rotary-wing aircraft. Recent successes include the company’s best-selling, turbine-class ST3400 TAWS and its 4-ATI retrofit primary flight displays, and its new HeliTAWS™ is the helicopter industry’s first complete helicopter safety solution.
