DK-406-DT


AeroELT™ DK-406-DT

Meets the Global Aeronautics Distress Safety System (GADSS) Requirements

Dukane Seacom’s new DK-406-DT is the first of its kind Second Generation Beacon (SGB) ELT-DT designed for use with the new worldwide Search and Rescue satellite network. TSO-authorized to TSO-C126c, the DK-406-DT is a crash-survivable distress tracking ELT that was designed for in-flight distress tracking and automatic in-flight triggering. Meeting current and future ELT requirements, the DK-406-DT includes improvements standard in the Dukane Seacom’s AeroELT
product line including:

Safety – The DK-406-DT is capable of safely containing a thermal runaway event of the internal lithium battery with no venting, in compliance with DO-227A.

Reliability – The DK-406-DT flame-resistant design includes an aluminum housing and fire-shielded transmit cable that improves performance in case of extreme heat or fire. The direct-mounted housing ensures crash safety and accurate triggering just as the robust system interconnects improve equipment durability.

Accuracy – Multi-axis MEMS device used to automatically detect impact improving trigger reliability over traditional “G-Switch” triggers. A self-contained GNSS receiver provides enhanced search and rescue capability to quickly locate any aircraft in distress worldwide.
