F-22 Avionics Require Inflight Reboot

Posted by chrisd on from the ctrl-alt-boom dept.

An anonymous reader writes "The Atlanta Journal & Constitution is fronting a lengthy piece on the USAF's new F-22 and its upcoming shootout with the existing fleet of F-15's & 16's. One line in the article really jumped out at me: 'When avionics problems crop up now, pilots must restart the entire system as if rebooting a personal computer.' I did some googling, and this is about as much as I could find: The hardware backbone for the system is the Hughes Common Integrated Processor, which, in turn, appears to be built around the Intel i960 CPU. I couldn't find a name for the operating system, but it appears to be written in about one and a half million lines of Ada code; more on the Ada hardware integration and Ada i960 compilers is here. Any Slashdotters working on this project? If so, why do you need the inflight reboot? PS: Gamers will be interested to learn that nVidia's Quadro2 Go GPU and Wind River's VxWorks Operating System are melded in the F-22's Multi-Function Display."

    ...opening weapon bay doors...producing only an easily-recoverable spin
    Well, hopefully that feature puts a lid on those trigger-happy pilots, especially at low altitude.

    Sorry, couldn't resist. :)
