Aircraft electronics manufacturer Shadin Avionics has introduced the latest version in its DARALT series of radar altimeter converters. According to the Minnesota-based manufacturer, its “future-proof” converters allow for the installation of new radar altimeters in any aircraft, enabling the use of 5G-resistant altimeters in those with non-digital interfaces.
The DARALT series—which is fully compliant with ARINC 552A standard and certified to DO-178C design assurance level B—enables the interface to communicate with any legacy analog indicators and equipment that might remain after a radar altimeter upgrade. It uses digital-to-analog technology that not only retains the original analog signal accuracy but provides better resolution resulting from new radio altimeters.
Further, the system has the ability to adjust altitude trip points, as well as match magnetic field lag (hysteresis) previously provided by legacy altimeters. In addition to providing enhanced situational awareness to flight crews, this helps avoid the need for costly operating manual updates and associated retraining.
“With the launch of the [newest iteration of the] DARALT series, Shadin Avionics once again demonstrates its commitment to innovation and safety in aviation technology,” said company president and CEO Mike Ingram. “Furthermore, our forward-thinking approach enables legacy aircraft to upgrade with 5G-compatible radar altimeters that equip our customers for the future of aviation.”
