If it has its interior and has its engines why not even if it won’t fly soon.
I could be wrong, but I thought Roll out on this forum means, roll out onto the flightline. Not just roll out of FAL or roll out of paint shop.
To answer your question, even with engine and seats, and been painted, they could still sit at the A380 area (could be any parking/storage area, just for example) for months before going to the actual flightline - the HL frame is doing exactly that, because it’s delivery schedule is not due until October.
We did not change the HL status to roll out. So for consistency, I think we should follow the same rule - roll out to the flightline, otherwise we could have many different roll out at different stages.
