Abstract : In an effort to reduce the Collision With Ground (CWG) and Spatial Disorientation (SDO) mishaps, the F-16 System Program Office has initiated an effort to improve F-16 C/D HUD symbology. In support of this effort, the SPO identified a set of attitude awareness enhancements for potential incorporation into the aircraft. These were (1) extended horizon, (2) ghost horizon, (3) articulated nose down pitch bars, (4) removal of 2:1 pitch scale compression, (5) moving nose down pitch bar tic marks to the inside of the pitch bars, (6) modified bank angle indicator, and (7) modified zenith/nadir symbols. Prior to the incorporation of these enhancements, the Crew Station Evaluation Facility performed a simulation evaluation to assess the improvement in attitude awareness provided by these changes. Fifteen pilots flew a series of unusual attitude recoveries and mission demonstration tasks during which reaction time, error rate, and subjective ratings were collected. Results showed faster reaction times, especially in nose-down conditions, and strong subjective preference for the modified HUD format. Based on these results, the CSEF recommended the incorporation of the extended horizon, ghost horizon, modified pitch ladder, and modified zenith/nadir symbols (low priority). Ratings for the bank angle indicator were mixed. It is recommended that the bank angle indicator be evaluated in instrument flying conditions before being considered for incorporation into the F-16 HUD....
