A preliminary design for an affordable head-up display was developed under a NASA technology transfer contract. Attention was paid to the drivers that have here-to fore kept HUDs out of the general aviation fleet. These drivers are: high luminance (brightness), large physical size, wide field-of-view and the need for dedicated electronics. The HUD makes use of commercial off-the-shelf components and PC electronic microprocessors and operating systems. In the GA HUD, the optics were simplified using a single curved combiner providing both collimation and superposition. The lateral field-of-view will be approximately 15-18 degrees depending on the cockpit geometry. This optical arrangement leads directly to a much smaller physical size. The HUD is being developed primarily as a visual flight aid although the symbology will support limited instrument use, such as instrument approaches and recovery from unusual attitudes.
