AeroELT? DK-406-AF

Meeting the Next Generation Performance Specifications and Battery Safety Requirements.

Dukane Seacom’s new AeroELT, the DK-406-AF, is a state-of-the-art, integrated Emergency Locator Transmitter (ELT) solution that was designed and tested to meet the current and future requirements for ELTs worldwide. With a focus on high reliability, the DK-406-AF provides improvements in automatic triggering, meets or exceeds requirements for containment of thermal runaway, and is packaged in a rugged aluminum housing using high quality military grade connectors and switches for improved performance. The key features of the DK-406-AF include:

Safety – The DK-406-AF is capable of safely containing a thermal runaway event of the internal lithium battery in compliance with DO-227A, ensuring a smooth path to certification.

Reliability – The DK-406-AF 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 further enhances the ability of search and rescue to quickly locate an aircraft in distress with worldwide coverage.
