AeroELT DK-406-AFM
AeroELT™ DK-406-AFM
Emergency Locator Transmitter (ELT) with GNSS Receiver
Dukane Seacom’s new AeroELT, the DK-406-AFM, 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 in harsh environments, the DK-406-AFM 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.
Safety – The DK-406-AFM 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-AFM 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.
Performance – A multi-axis configurable MEMS device is used to automatically detect impact improving trigger reliability over traditional “G-Switch” triggers. In addition, the MEMS crash sensor can be adapted to special military tactical conditions. A self-contained GNSS receiver further enhances the ability of search and rescue to quickly locate an aircraft in distress with worldwide coverage.
