The new 752 comes with a plethora of fantastic new features, including but not limited to the gear tilt, a live cockpit, a full, highly detailed cabin, and in-cabin screens that indicate your destination, flight time remaining, and distance to destination in kilometers.
I think adding a seatbelt and no smoking sign to these screens would be a cool addition! The pilot can control these with the buttons on the right side of their screen. Like real life, though, the no-smoking signs would realistically always stay on.
See below for concepts!
Please pardon my obvious lack of editing skills. I, once again, believe that this is a simple yet incredibly cool feature that would put the 752 over the top. I hope I have earned your vote! Have a great day! I welcome any constructive criticism and/or comments, but please do not start any arguments.
