Avidyne Corporation has received certification of the AviOS10.3 operating system software for its IFD series of FMS/GPS/NAV/COMS and Atlas/Helios flight management systems.

AviOS10.3 has received Technical Standard Order Authorisation (TSOA) and Supplemental Type Certificate (STC) approval from the FAA, allowing for immediate shipment on new units, as well as upgrades for the large installed base of existing Avidyne customers.

“We have faced several challenges in getting AviOS10.3 to market including, of course, the global pandemic and supply chain crises, but Avidyne has continued to innovate and we are pleased to bring these new capabilities to our current and future customers,” says president and ceo Dan Schwinn. “AviOS10.3 includes several significant new functions and features that will continue to keep our FMS line at the forefront in general and business aviation avionics.”

“Customers will really appreciate the new features in AviOS10.3, including visual approaches, which provides stabilised guidance into any runway in the database, whether it has a published approach or not,” adds vice president of worldwide sales John Talmadge. “In addition, our implementation of visual approaches allows pilots to select straight in, base or downwind entries, plus glideslope angle with intuitive operation.

“We've also added several new features that are targeted primarily for helicopter operators including RADALT display, power line database, half-mile zoom range and a three arc-second high-definition terrain database option.”

AviOS10.3 adds many new features and enhancements to the FMS, the map, user interface and third-party interfaces. It is also available as a field-loadable software upgrade that can be accomplished by any authorised Avidyne dealer. Key features of AviOS10.3 software for IFD include:
