Field-of-view (FOV) effects are investigated in simulated flights with sensor imagery appearing on a head-up display (HUD) and a head-down display (HDD). The pilots fly a simulated slalom course and are given information from a sensor image with a 25-, 40-, or 50-deg FOV and no additional information. The factors which most significantly affect performance are thereby identified, and the speed of flying, level of training, and FOV are found to be the most important characteristics. FOV affects performance regardless of the choice of HUD or HDD, and the narrow FOV caused the pilots to fly closer to the obstacles than the wider FOVs. No statistically significant difference between the use of HUD and HDD is identified, but the pilots appear to regard the displays in general as the entire world and not as a 'window on the world'.
