It's just a necessary feature for any airplane, I think people will agree with me, because any situations can happen in life and the game will have to be ended. I think it won't be particularly difficult for the developers to do this and make people happy.
Why is there still no auto-save for the A300-600? For example, on the A340 and A350 they have had it for a long time, I would really like the A300 to have such an important feature as well.
