N2  - Display evaluation has generally been performed using reaction time experiments or subjective evaluations to determine which display is better suited for a particular application. A new testing procedure combined with two analysis techniques of scanning behavior have been used to evaluate two alternative display designs in a realistic setting. Tests were conducted in the Langley Research Center's General Aviation Simulator. The results indicated that a new bargraph type of vertical speed indicator located between the attitude indicator and the altimeter is looked at more quickly, appears to lower cognitive workload slightly, and was preferred over a conventional vertical speed indicator.<p /> <p>Language: en</p>
