Airbus A380 runs windows?

I ran across this picture of the A380 cockpit.

Look in the screens on the far left and right, behind the side-stick. Looks like Windows to me.

If they really are running Windows on any airplane, I can guarantee that it will not be doing anything critical.

Chances are, they're not.

Duh!

It's an extremely cool looking cockpit though... I hope FS11 will have this thing.

Ya, it *looks* like it could be windows...

but what exactly is it doing? My guess is probably diagnostics fuel / part monitoring or youtube browsing.

Typically most navigation systems run on LynxOS or some other flavor of BSD/Linux.

Yes. Did love the picture. One of those cockpits that makes you believe you're almost smart enough to fly the thing ....

I was in an A330 (I think) not too long ago and they had these personal video player things in the seats.  They were running some flavor of Linux.  How do I know this?  I saw not one, not two, but three of them crash while other people were watching movies and a little penguin popped up while it was rebooting. 

I was listening to my Zune, so I didn't experience the crash myself, but it was somewhat amusing.  I realize it was probably crappy video drivers or something, but still funny.

Billions of dollars in R&D, hundreds of millions on the planes themselves, and they can't upgrade the basic cloth seats? Jeez...

Er... highly doubt it

Probably P/DOS or vxWorks or some other hard real time OS. We used P/DOS for the tracking system of a telescope and that thing is a pain to program for, but when it runs, it runs forever.

LynxOS is a real-time OS and so is was IRIX
and my assertion wasn't speculation...

Sorry, brain fart on my side

Of cours LynxOS is hard RT... nevermind, move along, nothing to see

no harm, no foul.

According to this website, Airbus runs RTOS, which is a custom build OS designed for real time running, which is important when a good answer now is better than a better answer later.

Actually, just as an interesting piece of trivia, "real time" doesn't mean superfast. An OS is defined RT when it can guarantee servicing requests in an exact interval. For example, I could design an OS that guarantees two hours MAX to service any request and it would fall under the RT definition.

It would be kinda slow, yeah, but REAL TIME OMG!

You know if y'all gonna get really picky, there's no such thing as a real-time OS. There's just an OS which has services which make writing real-time programs possible.

(I know that there's a basic set of functionality that you need, and if you have most people will label you a "real time OS" but I also know that means nothing.)

Hell, I've written windows programs which can deterministically respond once per millisecond with a jitter of a couple of clock ticks either side... Granted, it was a device driver, and the clock tick came from a PCI card... But, y'know real-time windows...

Besides which, what would the pilots use to play solitaire on during those long and boring flights while the plane flies itself? They couldn't use playing cards, they might accidentally jam a switch or something.

Advanced modern RTOS systems also guarantee that CPU cycles and Memory will be available at any given point in time enforced by partitioned isolation in the MMU.

Some (like LynxOS) can also isolate specific processes within the MMU partition.

Talk about hardcore virtualization!

Running Flight Simulator ??

Actually, running a simulation of reality within a real-world application is very interesting.

It means you can tell if something's gone wrong by how much reality has differed from the controlled simulation, for example.

There was this other thing, where an OS kernel runs a simulation of itself. If the simulation goes kaput because of a faulty driver, the kernel unloads it before it can do any damage.

Very Interesting, indeed.
