QNX Most people haven't heard of QNX Software, though they've likely come in contact with it. The real-time operating system is used where software failure can lead to catastrophic consequences, even death - from high-speed trains to air traffic control towers to highway toll systems. It's also used in more than 100 different types of cars on the road.

You did not undestood what real time OS is. It's not a matter of stability or reliability. It's matter of real time. Only a real time of can garantee to give you the correct answer in the accurate time.

This is why you need that in a nuclear plant or a plane auto pilot, a shuttle onboard computer, a car onboard computer. Because if you need a new path, correct injection or tubo, it's within 50 or 100 ms not within 50 or 10000 ms because you're damned OS is swaping memory or so.

Of course, real time usage in production is often critical, so OS is reliable and stable. But be sure that this is the "real time" thing that make things possible.
