FAA Grants RSC Status to Linux-Friendly RTOS

Posted by ryuzaki0 on from the still-can't-agree-what-real-time-computing-is dept.

BoulderDad writes "LinuxDevices.com is reporting that a proprietary RTOS capable of running Linux binaries has been certified by the FAA as a re-usable software component (RSC). LynuxWorks says LynxOS-178's RSC acceptance will enable greater software reuse among integrators and developers of safety-critical aerospace and defense components."

    I think he must be referring to the applications, not the OS itsef. LynxOS is not Linux. It's proprietary real-time OS that can run Linux applications. The LynxOS itself is backed by the vendor, and it's pretty good from what I hear. However, the applications built on it depend on the skill of the application developers, not the OS vendor.

  3. And pricing... by sadr · · Score: 3, Informative
    And a little research turns up per-developer pricing, although not the per-unit run-time license cost. That's not actually unreasonable, given the cost of DO-178B Level A documentation, but still. Ouch.
    Price and Availability
    In addition to the LynxOS-178 kernel, the offering also includes a complete artifacts package for the kernel and user library, DO-178B required documentation, code coverage test suites and analysis for 100% modified condition/decision coverage of the kernel and libraries, a full suite of standards-based development tools, and support. The company will also soon release the industry's first commercial-off-the-shelf certifiable TCP/IP stack. Development seats, including the LynxOS-178 kernel and one year of priority support, start at $18,000.

    FAA Aproval is nothing. There are various classes and certifications of instrumentations. I am a developer, so I do not really get into all that stuff, but here is the general breakdown;
    • Class A; a laptop that you carry with aviation equipment or a GPS.
    • Class B; an instrument that is IN the dashboard. But all it gets is POWER. It is not allowed to interact with anything else.
    • Class C; In the dash and ability to read the data from the aircraft bus; that is it can display the status of the aircraft.
    • Class D/E; in the dash, and not only reads, but writes data on the bus; that is it can be used for control.
    If anybody else has the real scoop, go for broke on it.

    I prefer the "u" in honour as it seems to be missing these days.
