A study on the effects of target resolution and contrast in air combat engagements was conducted to determine the potential impact of visual display characteristics on the effectiveness of air combat simulation training. A large-scale computer model of air combat engagements was used to investigate the effects of 2 and 4 arc min. of target resolution and target/background contrast ratios of 0.5 and 9.0. The study results are discussed in the context of the benefits of enhanced visual display characteristics in practicing the skills required in air combat.
