I think this is a feature that would be really simple to create. Essentially you would have the option to create ~5 custom views. These would be fixed to move with the aircraft making it unlike the free view that is already in the sim. Along with this the sounds should change from inside to outside the aircraft (also currently not in free view). I think there could be a whole new horizontal square on the camera ui and several vertical squares for each custom view.
I really like the idea too! Since there’s a request for it, go vote for it here!
great Idea but it should be in #features
