HUD

A head-up display, or heads-up display, also known as a HUD, is a highly advanced transparent display that presents data without requiring users to look away from their usual viewpoints. The origin of the name stems from a user being able to view information with the head positioned "up" and looking forward, instead of angled down looking at lower instruments. A HUD also has the advantage that the pilot's eyes do not need to refocus to view the outside after looking at the optically nearer instruments.
