Safety-critical systemsSafety-critical systemsPosted Nov 24, 2008 16:31 UTC (Mon) by AJWM (guest, #15888)In reply to: Safety-critical systems by epa Parent article: Linux Guru Reiser Seeks New Murder Trial (Wired) It's not a matter of reliability, as such. For some such applications and configurations, it might well be. It's a matter of certifiable reliability. I'm not as up on the FDA requirements, but certainly FAA has some pretty strict requirements for documenting the process by which flight control software was developed, including documenting the specifications and so on, steps that harken back to the old waterfall method, quite different from typical FLOSS methodology. (It's slow as hell, but it does - when followed properly - produce reliable software (which then runs on hardware two generations old)). That doesn't apply to experimental aircraft, of course -- wouldn't surprise me if there are some homebuilts using Linux for flight control software, so long as there's a manual override.
