Instead of movies and crappy games on those in-flight displays, they should just stream the view out the cockpit window.
Like, I'm on a plane. I don't want to watch Toy Story when I can do that at home, I want to see what the pilots see. And that way every seat has technically a window to look out of.
It costs money though, so you usually only see them on more premium carriers and larger planes.
I'm working from memory here, but I think there was an instance where there was a crash or some incident where people could see it happening on the cameras though... and it's not ideal having everyone in the plane panicking because they're going to die.
How long of a delay (too long and people complain) and how to cut if off without having to add another line to the pilot's checklists during troubleshooting?
Yup, there was a very well known case covered on an early episode of Mayday / Air Crash Investigation (like season 1) about this. A lot of people got to watch the same terrifying view as the pilots as their plane plummeted from the sky.
