Aibus uses Linux for a variety of purposes on their planes and are experiencing a myriad of issues because of it. See other links on that thread, and do your own search for "airbus" and "linux" to see all the problems they're having. To try to deny them is ridiculous...
The most generous definition of myriad is 10,000
So please can you post 12 instances where there has been a Linux issue on Airbus?
Not for flight control systems, which is what you lied about in your post in that article. I like how the photo you showed wasn't even of the same kind of plane as the one the article was about.
and are experiencing a myriad of issues because of it.
While it's never impossible to experience issues with any OS, they're apparently experiencing issues due to poorly written vendor (Panasonic, IIRC) software, not Linux itself. As I said, look at the screen, it's not a kernel panic (= Windows BSOD), but Linux waiting for the software. This is as opposed to the Windows system that screwed up air traffic control due to a bug in Windows itself.
How bad does your OS have to be that SOP is rebooting the machine once a month? Funny thing is that the vendor for that advertised over five nines, which is impossible with 12 Windows reboots in a year (or seven if you let it go to restart automatically).
