What is a Virtual Window in an aircraft? I heard about Virtual Windows in the Dubai show, but I didn't really got it. What is it?

In a demo, when they opened the shields, I could just see the ground handling before taxing.

Search engines only gave me a patent, but I would rather learn about it laconically.

PS: Found in a triple seven.



I found a video where an english guy mentions them, but he doesn't seem to have a clue about their functionality.
They are basically window-shaped screens, displaying a feed from a camera so the middle aisle suits (where the alternative is a wall) passengers can enjoy the "view".


  The most interesting thing to me are the virtual windows. First Class passengers in the middle suite will have a set of “windows” like everyone else, only theirs will show images from an outside camera.
