Aircraft avionics software from LynuxWorks powers Avidyne aircraft flight deck

SAN DIEGO, 2 June 2009. Aircraft avionics designers at Avidyne Corp. in Lincoln, Mass., needed embedded real-time operating system software (RTOS) for their next-generation Entegra Release 9 integrated flight deck commercial avionics. They found their solution in the LynxOS-178 safety critical software from LynuxWorks Inc. in San Jose, Calif.

LynuxWorks and Avidyne made the announcement this week at the Military & Aerospace Electronics Forum and the Avionics USA conference in San Diego, sponsored by the PennWell Aerospace and Defense Media Group.

LynxOS-178 is commercially available operating system software that is a certifiable RTOS package that enables avionics designers to comply with DO-178B certification to meet FAA requirements.

Avidyne's Entegra Release 9 flight-deck systems include dual, triple, or quad integrated flight displays (IFD) for general aviation and light business aircraft.

"LynxOS-178 provided us with a combination of essential advantages that other software providers could not match," says Tom Neufelder, Avidyne's vice president of engineering.

"Specifically, ARINC 653 partitioning that allows us to integrate DO-178 Level B applications functionally next to Level D applications within the same machine, POSIX API, a software tool chain based on industry standards, and an artifact package that even includes an RSC [reusable software component] which significantly reduces our product's certification burden," Neufelder says.
