What radio altimeter input is required Class A TAWS compliance for the Sandel ST3400?
The Sandel ST3400 TAWS System is unique in that it can accept either a 2000 or 2500 ft. radio altimeter input as part of the Class A TAWS requirements. Most Class A TAWS systems require strictly a 2500 ft. input but Sandel was able to prove equivalency in the functionality of their system with only a 2000 ft. input.
