Shadin Avionics has introduced the newest iteration of the DARALT series of radar altimeter converters, enabling new radar altimeters to be installed in all kinds of fixed wing and rotor aircraft. Shadin's DARALTs are future-proof designs that adapt to evolving aviation technology such as 5G resistant radar altimeters on aircraft with non-digital interfaces.

Key Features of the DARALT series include:

- Digital to analogue advancement: Newly designed digital to analogue (D/A) technology, providing unparalleled accuracy, not only retaining original analogue signal accuracy but providing better resolution that comes along with newly designed radio altimeters. This technology provides the necessary interface to communicate with legacy analogue indicators and equipment that may still be present after the radar altimeter upgrade.

- Compliant with ARINC 552A: Fully compliant with the ARINC 552A standard, as well as multiple others if required, ensuring seamless integration with a wide range of avionics systems. This compatibility streamlines installation and minimises downtime, allowing for a smooth transition to any new or retrofit radar altimeter project.

- DO-178C DAL B certified: Safety is paramount in aviation, and the DARALT series reflects that commitment. These converters are certified to DO-178C Design Assurance Level B (DAL B), guaranteeing one of the highest design assurance levels possible, all while gaining TSO certification through the FAA.

- Legacy indicators and altitude trips for added safety: Altitude trips provide instant alerts in critical situations, and this solution has the ability to adjust these altitude trip points as well as match hysteresis that was previously provided by the legacy radar altimeter that is being replaced. This feature enhances situational awareness and assists flight crews in making timely decisions to ensure the safety of passengers and crew members while preventing costly upgrades to pilots operating manuals and the training that goes along with having new indicators in the cockpit.

President and CEO Mike Ingram says: "With the launch of the DARALT series, Shadin Avionics once again demonstrates its commitment to innovation and safety in aviation technology. Furthermore, our forward-thinking approach enables legacy aircraft to be upgraded with 5G compatible radar altimeters that equip our customers for the future of aviation. Shadin is also working with LB Aircraft Engineering in Miami, Florida to obtain an STC on 737 Classic and MD-80 series aircraft to instal the first ever RAC series converters."
