F-22 Avionics Require Inflight Reboot
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."

Since they use Ada, this war machine will actually work, despite more 1.5 million lines of source code running it. That's sad, why couldn't they use C, C++ or even Java for such projects, where failure might actually benefit mankind?
Just as a note to chrisd, any Slashdot reader who is also working on the F22 avionics would be working in a TOP SECRET environment. Which loosely translates to a) they couldn't tell you they even working on it b) couldn't even read Slashdot while at work because TS environments are not allowed access to the Internet.
Just as an FYI, but then, who wouldn't expect Slashdot editors to say something stupid?
