The industry's best-selling integrated TAWS for corporate, regional and air transport markets, the Sandel 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.
Exclusive to the ST3400 is the implementation of the Virtual Approach PathTM (VAP). Internally the ST3400 contains a synthetic glideslope to all runways based on FAA TERPS (terminal procedures). If the airplane is in a position to land and has FAA terrain clearances, the system is guaranteed not to alert - a very smart suppression method. This is something no other system does.
