As part of a research program studying display concepts to increase tactical situation awareness (SA) in the attack helicopter domain we investigated the relationship between SA and performance. In order to test this relationship empirically, we developed two measures of SA that could be assessed independently of performance, a detailed measure and a high-level measure. In three phases of a simulated attack helicopter mission the detailed measure, but not the high-level measure, was significantly correlated with a measure of performance. The results offer conditional empirical support for a relationship between SA and performance.
