ST3400 3-ATI TAWS/RMI

ST3400 3-ATI TAWS/RMI

The industry’s best-selling integrated Terrain Awareness and Warning System (TAWS) for corporate, regional and air transport markets, the ST3400 is an integrated panel-mount system that outperforms cumbersome remote-mount TAWS systems that weigh and cost far more. A 3-ATI-size system that features a TAWS database, processor and oversized, high-resolution color display in a single unit, the ST3400 meets TSO C151b for both Class A and Class B requirements. Also incorporating RMI functionality, the ST3400 serves as a drop-in replacement for conventional RMI units, displaying terrain maps, topographic maps, navigation waypoint maps and TCAS data.
