ARNC 764 2005-JUL-08 HEAD-UP DSPLAY HUD SYSTEM
Purpose: This document describes a Head-Up Display (HUD) system for installation in all types of aircraft. It describes the physical form factors, fit dimensions, electrical interface definition and typical HUD functions.
The HUD system provides primary flight, navigation and guidance information to the pilot in the forward field of view. The HUD accomplishes this by projecting images onto a combiner positioned in front of the pilot. The displayed image is collimated (appears at infinity to the pilot) and conformal (some of the symbology overlays the outside view). The conformal nature of the symbology presented to the pilot allows the pilot to see flight information and guidance cues together with the outside world visual cues. The system displays sufficient data to enable the flight crew to control the aircraft, particularly in low visibility operations.
