One of the most important is called Head-Up Display (HUD), Which is used in military aircraft. HUD is a transparent display that is positioned between the pilot and the cockpit window.

The launch and landing him on the runway to transmit the images, allowing the 737 fly in very poor visibility.

The first model produced was -700, which, as all later versions were fitted with new Motors CFM56-7B.
