Comparison of Specifications for Head-Up Displays in the Navy A-4M, A- 7E, AV-8A, and F-14A Aircraft
Abstract
This report provides, within a single document, a compendium of data on Head-Up Displays (HUDs) in U.S. Navy and U.S. Marine Corps aircraft that is germane to a Human Factors assessment of HUD design on pilot performance. The data in this report are compiled from current Naval Air Training and Operating Procedures Standardization (NATOPS) manuals and design specifications for each of the HUD units. Operational HUDs were found to vary dramatically from each other and the military specification for HUDs, MIL-D-81641(AS), with respect to symbology and formatting. Furthermore, display clutter was reported by pilots to be a major problem. A comprehensive information processing evaluation of virtual image symbols and formatting under dynamic conditions was recommended. Finally, none of the current Navy aircraft has a HUD control panel that complies to MIL- D-81641(AS), the military specification for HUDs. Pilots are required to bring their eyes back into the cockpit to ensure proper switch selection and, consequently, negate the primary purpose of maintaining a head-up mode.
