Sandel ST3400H

Description

ST3400H HeliTAWS® Helicopter Terrain Awareness and Warning System is certified and excedes the current HTAWS TSO-C194. Specifically built for helicopters, the ST3400H combines an advanced HTAWS computer with the industry’s best display technology to provide a single panel-mount, self-contained solution.

Combining its TAWS expertise from thousands of installations in private, corporate and air-transport airplanes and years of supplying civilian and military users with its 3” and 4” primary displays, Sandel now provides the helicopter industry the first multihazard avoidance system that alerts against wires, terrain and obstacles.

WireWatch®

Advance defense against wire strikes that helps helicopter pilots avoid transmission lines whether they are powered on or off. WireWatch uses unique wire alerting algorithms that work Sandel’s proprietary 3-arc second wire database.

TruAlert®

TruAlert is Sandel’s proprietary alerting technology that enables pilots to take off, cruise, hover and land at off-airport locations without triggering nuisance alerts.

NVIS Option

For missions flown under night vision goggles, the HeliTAWS® can be ordered with Sandel’s proprietary on-demand Class-B NVIS option. Unlike aftermarket NVIS modifications, Sandel’s unique NVIS mode employs no external filters and does not degrade its brightness or daylight characteristics when NVIS is 'off'.

GPWS Modes

For those requiring additional capability the HeliTAWS supports GPWS Modes 1, 3, 4, 5 and 6.
