For example, inside the cockpit the pilot can complete checklists while looking through Aero Glass. The Aero Glass display can paint a colored circle around switches or instruments that need to be checked or selected. It also can replicate a synthetic-vision display, but this display could show the outside world as viewed at any angle, say, down through the bottom of the aircraft, much like one of the very expensive features on the F-35 Joint Strike Fighter’s helmet display. Traffic display is more realistic and shows other aircraft in a more natural framework rather than as target diamonds on a panel display or tablet computer screen.
