A350 - What is "OIS NOT AVAIL"?

When I flew the A350 for the first time, I did not receive such an error. That screen was working fine. But now the screen does not work. What does “OIS NOT AVAIL” mean?


That screen have always been out of operation.
We don’t have any functionality implemented to that, yet :)


But the first time I used the plane, the screen was working.

I can with 110% certainty tell you that it was not :)
It’s looked this way since the aircraft was developed.


So I remember wrong, thank you. :)
