(Or at least the fact that it did crash). When you have other requirements that take priority (keep operating) like many embedded systems, you include a watchdog timer that reboots the system if the OS doesn't poke it every millisecond or whatever. Embedded systems typically don't take long to boot up. A classic example of something similar is Did the 1202 error and associated reboot prevent disaster on Apollo 11 landing? | |

| Jan 3, 2020 at 13:03 | comment | added | Ron Beyer | Modern operating systems, like Windows are not used in flight computers. Linux might be used, but I think it's rare (because of the modifications needed to meet avionics standards). More commonly would be LynxOS or VxWorks, which are highly specialized systems designed to run on high-reliability avionics and other industrial systems, and aren't a traditional OS like you would think of Windows or Linux. | |
