Claim:
A method for presenting traffic information on an aircraft display unit, said method comprising: receiving data representative of ownship position from a navigation data source; receiving first traffic data representative of first traffic comprised of at least one target from a first traffic data source; receiving second traffic data representative of second traffic comprised of at least one target from a second traffic data source; dividing the first traffic into third traffic and fourth traffic, where the third traffic corresponds to the first traffic located within a first zone of a plurality of zones, and the fourth traffic corresponds to the first traffic located within a second zone which is a zone other than the first zone; dividing the second traffic into fifth traffic and sixth traffic, where the fifth traffic corresponds to the second traffic located within the first zone, and the sixth traffic corresponds to the second traffic located within the second zone; determining whether there is a correlation between each target of the third traffic and each target of the fifth traffic if correlation information has not been received in either the first traffic data, the second traffic data, or both; generating a traffic symbology data set comprised of first traffic symbology data representative of first traffic symbology corresponding to each correlated target of the third traffic and the fifth traffic, and second traffic symbology data representative of second traffic symbology corresponding to each uncorrelated target of the third traffic or the fifth traffic, such that the first traffic symbology and the second traffic symbology are visually distinguishable from each other when presented on the screen of the display unit; and providing the traffic symbology data set to a display unit, whereby an image represented in the traffic symbology data set is subsequently presented on the screen of the display unit.
