This is just kind of a way to prevent pilots from leaving their doors open for flights. Its not really stopping them from doing it, just giving a warning that the doors are open if indeed they want to close them.
Why do we need this?
If you have ever been looking through replays and found the perfect screenshot with another plane, and then realized they have their doors open, it sorta ruins the picture.
Also, its annoying when you legitimately forget that you left them open and realize halfway through your flight.
Many pilots like me tend to stick to the cockpit cam, and may not notice the doors position. Here is what I envision:
A gray box similar to that when you are nearing violation, but merely says “Open Doors” or something similar. It could also have an exclamation mark. I would like it to have a “Tap to dismiss” feature, so if you don’t care or don’t want the message you can get rid of it fast.
My idea is that toggling pushback with doors open will trigger the message.
