Abstract
A method is provided for determining the integrity of incoming target data and for assigning and displaying a target icon correlated to the target data integrity. Target data integrity depends on the both accuracy and the timeliness of the position data being broadcast about the target. Target data integrity is monitored continuously to display a target icon correlated to the current integrity level. Changes in the target icon alert the flight crew or other user to changes in target data integrity. The icon attributes used to communicate a change in integrity do not interfere with other icon attributes used to communicate other characteristics of a target.
