AeroELT™ DK-406-DT
Designed to Meet the Global Aeronautics Distress Safety System (GADSS) Requirements
Dukane Seacom’s new DK-406-DT is a state-of-the-art, crash-survivable distress tracking Emergency Locator Transmitter (ELT, ELT DT, or ELT-DT) solution that was designed and tested to meet current and future requirements for ELTs worldwide including the GADSS requirement for in-flight distress tracking and automatic inflight triggering. In addition, the DK-406-DT includes the improvements standard in the 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.
